In 1990, the Sopcheozero Cr deposit was discovered in Monchegorsk Paleoproterozoic layered mafic-ultramafic intrusion (Monchepluton). This stratiform early-magmatic occurs middle part of Dunite Block, which is a member Monchepluton series. The Cr2O3 average-weighted content ordinary and rich ores 16.65 38.76 wt.%, respectively, at gradually changing concentrations within rich, poor ore types bo...

Introduction: AUTODYN [1] is used to consider the effect of altering the yield stress of geological materials on the resultant crater dimensions. This investigation is part of a series of fundamental inquiries into the sensitivities of AUTODYN, in order to fully validate the code as an appropriate tool to study large planetary impact crater formation. The majority of current AUTODYN application...

Abstract The mechanical processes that convert an initially fluffy chondrule fine-grained rim (FGR) into a more compact structure remain poorly characterized. Given the presence of shocks in protoplanetary disks, we use numerical simulations to test hypothesis dust-laden solar nebula contributed FGR modification. We iSALE2D shock physics code model collision dusty nebular fronts (which term “du...

The spatial and temporal variability of chemical signals in lavas, residues and melt inclusions provides important constraints on source heterogeneity, the efficiency of convection, and melt transport processes in the mantle. The past decade has seen an impressive increase in the number, precision and spatial resolution of chemical analyses. However, as resolution has increased, the picture of ...

The mineral ore potential of many mountainous regions of the world, like the Kurdistan region of Iraq, remains unexplored. For logistical and sometimes political reasons, these areas are difficult to map using traditional methods. We highlight the improvement in remote sensing geological mapping that arises from the integration of geomorphic features in classifications. The Mawat Ophiolite Comp...

Karapınar-Karacadağ Volcanic Rocks (KKVR) have very complex magmatic history and outcropped the southwestern part of Cappadocia Province (Central Anatolia). Here we present petrography whole-rock chemistry enclave-bearing rocks to constrain their source evolution history. These petrographic observation geochemical data reveal that enclaves in volcanic are magma mixing/mingling (MME), segregatio...
