<abstract><title style='display:none'>Abstract</title>Relative sea level fluctuations during the Frasnian generated two shallow-marine, mixed siliciclastic-carbonate successions in the Devonian Asturo-Leonese Basin. Each system represents a third-order sequence-stratigraphical unit deposited in the same basin during comparable extreme greenhouse conditions without nearby fluvial entry points. Depositional control on the siliciclastic and carbonate distribution was driven by relative sea level fluctuations, basin geometry, availability of sand and the way sediment was distributed by shelf currents. Early Variscan flexural bending of the continental crust changed the basin shape from a shelf with a gradual profile and low dip (early Frasnian) towards a shelf with a steep depositional dip (late Frasnian). Shelf distribution changed from along-shelf transport (early Frasnian) towards offshore-directed gravity flows (late Frasnian). As a consequence, siliciclastic-carbonate distribution changed from a predominance of skeletal carbonate in the proximal shoreface – foreshore area and siliciclastic predominance distally (early Frasnian), to a distribution pattern with proximal shoreface skeletal carbonates, offshore muddy carbonates and a siliciclastic zone in between where gravity flows distributed the siliciclastic sediment down dip (late Frasnian).</abstract>

<abstract><title style='display:none'>Abstract</title>The present article focuses predominantly on sandy deposits that occur within the Middle Miocene lignite seam at the Tomisławice opencast mine, owned by the Konin Lignite Mine. As a result of mining activity, these siliciclastics were available for direct observation in 2015–2016. They are situated between two lignite benches over a distance of ~500 m in the lower part and ~200 m in the higher part of the exploitation levels. The maximum thickness of these sandy sediments, of a lenticular structure in a S–N cross section, is up to 1.8 m. With the exception of a thin lignite intercalation, these siliciclastics comprise mainly by fine-grained and well-sorted sands, and only their basal and top layers are enriched with silt particles and organic matter. Based on a detailed analysis of the sediments studied (i.e., their architecture and textural-structural features), I present a discussion of their genesis and then propose a model of their formation. These siliciclastics most likely formed during at least two flood events in the overbank area of a Middle Miocene meandering or anastomosing river. Following breaching of the natural river levee, the sandy particles (derived mainly from the main river channel and levees) were deposited on the mire (backswamp) surface in the form of crevasse splays. After each flooding event, vegetation developed on the top of these siliciclastics; hence, two crevasse-splay bodies (here referred to as the older and younger) came into existence. As a result, the first Mid-Polish lignite seam at the Tomisławice opencast mine is currently divided in two by relatively thick siliciclastics, which prevents a significant portion of this seam from being used for industrial purposes.</abstract>

<abstract><title style='display:none'>Abstract</title>The Oligocene Lar igneous complex is located in the Sistan suture zone of Iran, being emplaced in Paleocene to Eocene flysch-type rocks. This complex includes mainly intermediate K-rich volcanic (trachyte, latite and andesite) and plutonic (syenite and monzonite) rocks that belong to shoshonitic magma. The geochemical characteristics of the Lar igneous complex, such as an enrichment of LREE and LILE relative to HREE and HFSE, respectively, a negative anomaly of Ti, Ba and Nb and a positive anomaly of Rb and Th are similar to those of arc-type igneous rocks. Tectonic discrimination diagrams also show that rocks of the Lar igneous complex fall within the arc-related and post-collisional fields and K-enrichment of these rocks confirm the post-collisional setting. Based on geochemical features, the Lar igneous complex magma was derived from partial melting of a phlogopite-bearing, enriched and metasomatised lithospheric mantle source and the magma was affected by some evolutionary processes like fractional crystallisation and crustal contamination.</abstract>

<abstract><title style='display:none'>Abstract</title>Geological heritage can contribute to our understanding of the long-term evolution of important sectors of our planet. Cretaceous–Neogene rocks (chiefly carbonates) crop out in the Nowdan anticline of the Zagros orogen. Field investigations have permitted the establishment of 10 key localities (stratigraphical reference sections) that represent these rocks within this anticline, which is a single large geosite. The formations are related to the main phases in the evolution of the northeastern sector of the African–Arabian continental margin. For instance, carbonate rocks of the Asmari Formation mark changes in the affinity of the study area, from the African–Arabian plate to only the Arabian plate, separated in conjunction with Red Sea rifting during the Oligocene. Information on the palaeogeographical changes is really precious to geoscientists and geotourists alike, and contributes to the great value of the Nowdan anticline geosite. Evidence from the latter, as well as from a few other places (i.e., the Mountainous Adygeya geodiversity hotspot in Russia, the North Coast of São Paulo in Brazil and the possible Gondwanan geopark in Namibia) illustrates the necessity of distinguishing a palaeomapping subtype in palaeogeographical characterisation of geological heritage.</abstract>

<abstract><title style='display:none'>Abstract</title>The present study aims to investigate the diversity index (dv-index) of morphotectonic and geomorphological land-forms as one of the scientific value indices for evaluation of the geotouristic potential of the southeastern Lut desert using topographic statistical analysis. Scientific index scoring in most models is based on descriptive assessment by geotourists and experts. Statistical analysis of the dv-index in the present study helps experts to base their scoring on scientific methods. The dv-index is controlled by several items. In the present study, we analyse two of these, including the classification of topographic continuity pattern (TCP) and topographic slope position correlation (TSPC). For this purpose, a network of section lines is used to analyse slope continuity. The TSPC analysis is performed by using two parameters of absolute value and slope position. Results for these two evaluated items indicate a score of 1.46 (out of 2) for the dv-index. Given a rating of 5, the score obtained for the two items is a high one. Therefore, an initial estimate of the dv-index indicates a significant scientific value of the study area.</abstract>

Scope Geologos is an international, peer-reviewed journal publishing research results and review articles covering all earth-science disciplines, with a focus on the geology of central and eastern Europe as well as other areas of poorly known geology. Only manuscripts in English are considered for publication. All manuscripts should meet international standards regarding the quality of both the scientific content and the presentation (structure, style, good English, high-quality figures, etc.). By submitting a manuscript, the authors agree implicitely that (1) the manuscript has not been published in whole or for a considerable part elsewhere; (2) a similar or largely comparable manuscript has or will not be submitted to any other journal as long as the manuscript submitted to Geologos has not been rejected; (3) no plagiarism is involved; (4) no copyrights are infringed; (5) no scientific fraud is committed; (6) no conflict of interest exists. Submission New manuscripts should be submitted in electronic form to the address <a href="http://www.geologos.com.pl/">www.geologos.com.pl</a> . An accompanying letter should stipulate why the manuscript is of interest for the readership of Geologos. Receipt of a manuscript will be acknowledged. If no acknowledgement is received within one week (except for the summer field season), the Editors should be contacted by e-mail. Format Manuscripts should be delivered as double-spaced text file with 2.5 cm margins and 12-point font size (Times New Roman). They should be arranged in the following order: <ul> <li> title </li> <li> full name(s) and address(es) (including e-mail) </li> <li> abstract (maximally 350 words, preferably 150-250 words) </li> <li> keywords (maximally five) </li> <li> main text </li> <li> acknowledgements </li> <li> references </li> <li> captions for tables and figures </li> <li> tables and figures </li> </ul> Illustrations Figures must be of high quality, with lettering and lines easy to read. The preferred size of figures is: (a) width 170 mm (two columns of text) and height maximally 250 mm, or (b) width 80 mm (one text column) and height maximally 250 mm. All figures and tables should be cited in the text in the correct order. Both drawings and photographs are considered as figures and should be numbered as such (Fig.). Tables Tables should be reducible in print to (a) a width of 80 or 170 mm and a maximum height of 250 mm, or (b) a width of 250 mm and a maximum height of 170 mm. Text in tables should be in 9 or 10 pt font size. Vertical lines in tables should be avoided. Appendices An appendix should contain information that is substantial in length, that is not necessary for the reader to understand the running text, and that would unduly interrupt the running text. As such material is rarely interesting for a large number of readers, the Editor-in-Chief, in consultation with the reviewers and/or the Editorial Board, can decide that the Appendix (or Appendices) will not be published, but should be replaced by a sentence in the text that the data can be obtained from the corresponding author. If appendices are considered acceptable, they should be submitted each as an individual file. References References in the text should be as follows: ". as shown by Smith (2003, 2008), Brown &amp; Johnson (2007) and Fedorowski et al. (2008); or, alternatively, ". as was found already some years ago (Smith, 1993, 1998; Brown &amp; Johnson, 1997; Fedorowski et al., 1998). In the reference list, works of one author should be ordered according to year; if there are also works with co-authors, first the works with one co-author are mentioned, alphabetically and then according to year; in the case of three or more authors, the references should be according to year, then alphabetically. If there are more publications by an author in one year, they should be referred to in both the text and the reference list as a, b, etc. Examples (note that jurnal titles are written in full, and that journal and book titles are written in italics): Gross, M.R. &amp; Eyal, Y., 2007.

Dunedin Academic Press, Edinburgh, 310 pp. In the case of reference to an text that was not written in a generally accessible language, the title of the work should be given in English [between brackets] immediately after the original title, for instance: Wysota, W., 2002. Stratygrafia i œrodowiska sedymentacji zlodowacenia Wis³y w po³udniowej czêœci dolnego Powiœla [Stratigraphy and sedimentary environments of the Weichselian glaciation in the southern part of the lower Vistula region]. Torun University Press, 144 pp. Reviews The manuscript evaluation steps are as follows: (1) initial evaluation made by the Associate Editor, (2) sending the manuscript to reviewers selected by the editors, (3) analysis of received reviews and evaluation by the Associated Editor, (4) evaluation of the improved version of manuscript (by the reviewer or Associated Editor), (5) final decision (by the Editor-in-Chief). Each manuscript will, as a rule, be reviewed by two referees, commonly one Polish and one foreign. In the case of contradictory advises, additional reviews can be considered by the editors. Reviewers are selected from a group of specialists with significant publications in exact field of science.The reviewers judge about suitability of the manuscript for the journal, scientific quality, compactness and structure of the text, quality and usefulness of the photos and artwork, and the quality of the English language. The reviews are double-blind. If major revision is advised, the revised manuscript may be sent out again for review, in principle to the same reviewer(s). After the decision of acceptance, Geologos journal provides free linguistic proofreading.　 Offprints One issue of Geologos is supplied free of chargé to each author. A pdf version of individual contributions can be downloaded from the Geologos website <a href="http://www.geologos.com.pl/">www.geologos.com.pl</a> and Sciendo platform <a href="https://www.sciendo.com/journal/LOGOS">https://www.sciendo.com/journal/LOGOS</a> The journal does not have article processing charges (APCs) nor article submission charges.
