Kuwaiti dolocrete: petrology, geochemistry and groundwater origin

Sedimentary Geology, 1991
Abstract Near-surface sediments in southern Kuwait show extensive development of duricrusts. The host materials are siliciclastic sandstones of the post-Eocene Kuwait Group. Inland, the duricrusts are dominantly pedogenic calcrete (with some silcrete and gypcrete), whereas within 10–20 km of the coast, dolomite is the dominant duricrust mineral. Both

Volcanology, geochemistry, and petrology 1983–1986

Reviews of Geophysics, 1987
Reginald A. Daly was remarkably prescient when he chose the title Igneous Rocks And The Depths Of The Earth for his classic book, for this title could properly serve with minor qualification as an alternative title of the Volcanology, Geochemistry, and Petrology (VGP) section of the 1983–1986 IUGG Quadrennial Report.

Volcanology, geochemistry, and petrology 1979–1982

Reviews of Geophysics, 1983
This introduction to the Volcanology, Geochemistry and Petrology (VGP) section of the 1979–1982 IUGG Quadrennial Report is intended to serve as a thumbnail sketch of some major research developments and trends in VGP over the past four years. These notes are drawn from, and limited to, the nine review articles which follow in this section. While I have

The Buçaco Basin (Portugal): Organic petrology and geochemistry study

International Journal of Coal Geology, 2010
Abstract The Bucaco Basin includes a Carboniferous/Permian sequence that comprises, from bottom to top, the following stratigraphic sequence: Algeriz Formation, Vale da Mo Formation and Monsarros Formation. Algeriz Formation is constituted by deposits of basal breccia with variable thickness and alternating layers of siltstone, mudstone and ...

Petrology and Geochemistry of Lavas and Pyroclastics

2017
This chapter offers a comprehensive overview of the main petrologic of geochemical characteristics of the Nisyros volcanic products, integrating published data and some new observations. The mineralogy and petrography of the magmatic rocks are described, including a brief presentation of enclaves, xenoliths and xenocrysts.

Petrology and geochemistry of Rodrigues Island, Indian Ocean

Contributions to Mineralogy and Petrology, 1985
Rodrigues Island is composed of a differentiated series of transitional-mildly alkaline olivine basalts. The lavas contain phenocrysts of olivine (Fo88−68)±plagioclase (An73−50), together with a megacryst suite involving olivine, plagioclase, kaersutite, clinopyroxene, apatite, magnetite and hercynite-rich spinels.

Petrology and geochemistry of lunar dimict breccia 61015

Journal of Geophysical Research: Solid Earth, 1984
Dimict breccia 61015 consists dominantly of granulated anorthosite and impact melt rock of VHA (very‐high‐alumina)‐basalt composition. The anorthosite is a typical Apollo 16 ferroan anorthosite, except that it is slightly more augite‐rich than most other ferroan anorthosites. The breccia probably formed in the floor of an expanding crater cavity by the

Petrology, geochemistry and genesis of Kuiqi granite batholith

Chinese Journal of Geochemistry, 1986
The Kuiqi granite batholith outcrops in the vicinity of Fuzhou City, Fujian Province and constitutes one of the typical alkali granitic complexes in the “Belt of Miarolitic Granites” extending along the southeast coast of China. The complex is believed to have been emplaced at higher levels of the crust in a tensional fault environment ...
