Crust–mantle interaction in the genesis of siliceous high magnesian basalts: evidence from the Early Proterozoic Dongargarh Supergroup, India
TLDR
In this paper, the authors present chemical (XRF, INAA) and mineralogical data on a siliceous high magnesian basalts (SHMB) suite from the Early Proterozoic (2.1-2.5 Ga) Dongargarh Supergroup, Central India, the first of its kind reported from the Indian Precambrian.About:

Geochemistry of the Meso- to Neoproterozoic basic-acid rocks from Hunan Province, South China: implications for the evolution of the western Jiangnan orogen
TL;DR: Based on geochemical and petrological studies of the Meso- to Neoproterozoic basic-acid rocks, a preliminary model for the formation and evolution history of the western Jiangnan orogen in the area was put forward as discussed by the authors.

Generation and evolution of siliceous high magnesium basaltic magmas in the formation of the Permian Huangshandong intrusion (Xinjiang, NW China)
Jian-Feng Gao,Mei-Fu Zhou +1 more
TL;DR: The Huangshandong mafic-ultramafic intrusion is the largest in the eastern Tianshan Orogenic Belt of the CAOB and consists of a layered unit intruded by a massive unit.

The geochemistry of ultramafic to mafic volcanics from the belingwe greenstone belt, Zimbabwe: Magmatism in an archean continental large igneous province
TL;DR: In this article, the evolution of the late Archean Belingwe greenstone belt, Zimbabwe, is discussed in relation to the geochemistry of the ultramafic to mafic volcanic rocks.

The Bastar craton, central India: A window to Archean – Paleoproterozoic crustal evolution
M. Santosh,M. Santosh,M. Santosh,Toshiaki Tsunogae,Toshiaki Tsunogae,Cheng-Xue Yang,Yue-Sheng Han,K.R. Hari,M.P. Manu Prasanth,M.P. Manu Prasanth,Sam Uthup +10 more
TL;DR: In this paper, a new tectonic classification of the Bastar craton into the Western Bastar Craton (WBC), EBC, and the intervening Central Bastar Orogen (CBO) is proposed.

Precambrian mafic magmatism in the Bastar craton, central India
TL;DR: The Bastar craton has experienced many episodes of mafic magmatism during the Precambrian as discussed by the authors, and this is evidenced from a variety of precambrian volcanic and dyke formations exposed in all parts of the Bastar basin in the form of volcanics and dykes.

Magnesian andesite and basalt from Shodo-Shima Island, southwest Japan, and their bearing on the genesis of calc-alkaline andesites
TL;DR: In this paper, the primary magma of the andesite, estimated on the basis of the olivine fractional crystallization model, is not basaltic but andesitic.
Journal ArticleDOI
Petrogenesis of picrites from the Caribbean Plateau and the North Atlantic magmatic province
TL;DR: In this paper, the authors studied the petrography, mineralogy and geochemistry of three different regions: the island of Curacao, an active hot spot on the mid-Atlantic ridge; and the early Tertiary volcanic margin off the coast of Greenland, which formed during the rifting that created the Atlantic ocean.

Crustal Contamination Identified in Keweenawan Osler Group Tholeiites, Ontario: A Trace Element Perspective
TL;DR: In this article, the authors divided the Black Bay Peninsula into three suites based on the relationship between stratigraphy, petrography, and geochemical variations (e.g., Mg-number, $$A1_{2}O_{3}$$, La/Sm, and Gd/Yb).

Geochemistry and petrology of 2.40-2.45Ga magmatic rocks in the north-western Belomorian Belt, Fennoscandian Shield, Russia
TL;DR: In this article, Assimilation-fractional crystallization (AFC) and mixing models in terms of ϵ Nd (T )−La/Sm ratios have been evaluated for the origin of the mafic rocks.

Geochemistry of the Dongargarh volcanic rocks, Central India: implications for the Precambrian mantle
TL;DR: The Dongargarh lavas, erupted over a broad time span from ∼ 2462 Ma to ∼ 1367 Ma, comprise an interlayered sequence of felsic to mafic volcanic rocks and sedimentary formations as mentioned in this paper.
