Pre-Belt gneiss, schist, and related rocks: comprises all the rocks older than the Belt series except the Stillwater complex. These include the Cherry Creek group, consisting of interlaminated gneiss, schist, marble, and quartzite; and the Pony series of Tansley and others, consisting of gneiss and schist of both sedimentary and igneous origin.

Tectonic models have postulated that subduction of a flat‐lying oceanic plate was intimately linked with mid‐Eocene magmatism in the northwestern United States and . A variety of volcanic rock was recovered from the flanks of seamounts, guyots, atolls, and islands in the Ratak chain of the Marshall Islands on the U.S. Geological Survey cruise LCP. The main objective of this cruise was to study the distribution and composition of ferromanganese oxide crusts. Preliminary results of managanese crust composition are reported by Schwab et .

The Guffey volcanic center is the largest within the km{sup 2} mid-Tertiary Thirtynine Mile volcanic field of central Colorado. This study is the first to provide extensive chemical data for these alkalic volcanic and subvolcanic rocks, which present the eroded remnants of a large stratovolcano of Oligocene age. GEOCHEMISTRY OF AMPHIBOLITES AND METAGABBROS FROM SITES AND Hercynian basement rocks were recovered at the oceanward edge of the thinned continental crust at Sites and on the same struc-tural high as Leg Site (Fig. F2). The rock types included met-agabbros, amphibolites, microamphibolites, meta-tonalites, and meta-.

In general, primary igneous and sedimentary structures are well-preserved in clear distinction to the Refahiye metamorphic rocks: In the metavolcaniclastic rocks, volcanic fragments and. The gneissic rocks observed inthe area of study are the quartzo -feldspathic rocks that underlie about 70% of the total mapped area (Figure 1).

The rocks are mainly biotite gneiss, feldspathic gneisses and banded gneisses. These rocks are conspicuous around Old Netim and in fact the predominant rock type in the northeastern part of the study area.

Mafic volcanic rocks that occur within the sedimentary pile of the Hindoli Group were analyzed for major and trace elements (including REE) to establish tectonic setting of volcanism during the early Proterozoic history of the North Indian Craton.

The mafic volcanics are sub-alkaline showing compositional variation from picrobasalt to basalt. They are LREE. about 1 percent of the Central Interior region. Sedimentary rocks are also notably rare. Shelf-type sedimentation evidently began about 1, m.y.

ago, but the major deposits were of clean sandstone. Car­ bonate rocks are virtually unknown, and all the sedi­ mentary rocks make up only an estimated 7 percent of this great region. John F.

Komatiites made their first appearance in the geological literature in the late s, with the recognition of ultramafic lava flows in the Komati River Valley of the Barberton greenstone belt (Viljoen and Viljoen, ).Examples of spinifex–textured flows had been recognized at about the same time in Western Australia, and landmark papers on these occurrences appeared shortly.
