Granites of the Lachlan Fold Belt resulted from partial melting of the crust. In most cases, fusion involved mainly quartz and feldspar, producing felsic m... BW Chappell - 《Lithos》 被引量: 1435发表: 1999年 High‐ and Low‐Temperature I‐type Granites I– and S-type granites differ in...
The formation of continents involves a combination of magmatic and metamorphic processes. These processes become indistinguishable at the crust-mantle interface, where the pressure-temperature (P-T) conditions of (ultra) high-temperature granulites and magmatic rocks are similar. Continents grow laterally...
In the geothermal development of hot dry rock (HDR), both the drilling of the wellbore and the heat exchange of the heat reservoir involve the effects of different cold and hot conditions on the high-temperature rock mass. The testing machine for rock mechanics was used to conduct a uniaxial...
It was formed during the northward subduction of the NeoTethys oceanic slab and the subsequent India-Asia collision (Yin and Harrison, 2000; Ding et al., 2014; Zhu et al., 2019). The Gangdese batholith is mainly composed of Mesozoic granites, hornblende gabbros, granodiorites and tonalites...

The lens has been retrogressed under hydrous, low-pressure conditions, as indicated by: (a) partial replacement of Cpx by Amp; (b) symplectites of Opx þ Pl þ magnetite replacing Grt (Fig. 3g); (c) Cpx contains exsolution lamellae of Opx and has rims of Opx (Fig. 3g). The ...
Some of silica migrated and, as the temperature decreased, precipitated in veins or as aggregates around the high-grade iron ores. Most iron was enriched (semi-) in situ and this formed the high-grade iron ores. A small amount of “iron activation–reprecipitation” developed high-grade ...
