Two series of volcanic rocks with different petrochemical affinities—calcalkaline and komatiite- tholeiitic series—were identified as protoliths for the Early Proterozoic metamorphic rocks of the Batomga granite-greenstone terrane. The metavolcan

The protoliths of the Early Proterozoic metamorphic complex in the Batomga granite-greenstone terrane are proved to comprise two petrochemical series of volcanic rocks: calc-alkaline and komatiite-tholeiite. The metavolcanic rocks of the calc-alkalin

The accumulations of massive sulfides, mostly pyrrhotite, and the accompanying Pt–Pd and gold mineralization in the more eroded Lantar part of the Dzhugdzhur massif-type anorthosite, Aldan Shield, Russia, are characterized in detail for the first t

This paper reports the first U-Pb geochronological data on the Precambrian granitoids of the Batomga block (Aldan shield). It was established that the amphibole diorites of this block have an age of 2062 ± 14 Ma, while biotite granites are dated at

Coarse platinoid-chromite intergrowths in association with native gold, as well as with Au‐(Ag)‐Cu and Au‐(Cu,Ag)‐Pd alloys, first discovered in the Taymen’ river alluvial sediments have been investigated. Identification of the essentially

The bottom of the stratigraphic sequence of the Dzhugdzhur deep-seated granulite complex was determined to consist of a stratified metabasite-enderbite association. The distributions of major and trace elements indicate that the protoliths of the ass

The origin and growth of the continental crust is one of the main problems in the study of the Earth’s history. At present, the composition of the continental crust is sufficiently well known for the Archean shields, where the crust is exposed. Stu
