Boron isotope compositions were measured in kornerupine and tourmaline from lenses consisting primarily of kornerupine, plagioclase corundum. The occur within hornblende-gneiss or along the boundary between this gneiss an amphibolite lens at Akarui Point Lützow-Holm Complex, Prince Olav Coast, East Antarctica. peak metamorphic conditions have been estimated to be ~ 800-900 oC 8-11 kbar. δ11B wh...

Papua New Guinea (PNG) is located at the convergence edge of Pacific Plate and Indo-Australian Plate, consisting three units. There are chromium mineralization types in PNG. Based on national-scale geochemical mapping PNG during 2015–2018, 1399 samples stream sediments were collected from Highland Region, Peninsula, Islands. This paper preliminarily studied chromium’s background, spatial distri...

Abstract The evolution of the Ladon basin has been marked by intense geological activity and discharge huge volumes water from Martian highlands to lowlands in late Noachian Hesperian. We explore potential ExoMars Trace Gas Orbiter/Color Stereo Surface Imaging System color image data set for interpretation show that it is particularly effective geologic mapping combination with other sets such ...
