Geology of the central uplift of the Kamestastin Lake impact structure, Labrador, Canada

Meteoritics &Planetary Science, EarlyView.
Abstract The ~28 km Kamestastin (Mistastin) Lake impact structure is a relatively well‐preserved and well‐exposed complex impact structure. The central uplift of this structure is accessible as two islands in the middle of Kamestastin Lake. We present an updated, detailed geological map and description of Horseshoe and Bullseye islands that provides ...

Morpho‐structural analysis of impact craters on Pluto: Implications for the study of complex craters

Meteoritics &Planetary Science, EarlyView.
Abstract We used Pluto's global digital elevation model to automatically perform a morphometric analysis of impact craters. Triangular irregular networks (TINs) were generated for each crater, providing a detailed representation of crater topography and enabling more accurate morpho‐structural analysis. A dedicated toolkit generated radial profiles for

Origin and formation of a chondritic xenolith in Krymka (LL3.2, breccia): Indications for a late formation of the accretionary breccia

Meteoritics &Planetary Science, EarlyView.
Abstract An unusual chondritic xenolith was found in two sequentially prepared thin sections of a sample from the Krymka (LL3.2) chondrite. The xenolith has a rounded, slightly deformed shape of about 5 mm in apparent diameter and is partially surrounded by a double rim made of an inner fine‐grained silicate‐rich rim and an outer sulfide‐rich rim.

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

Sedimentology, EarlyView.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

Sedimentology, EarlyView.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...
