On the other hand, the M1 event could also be explained in terms of a mid-crustal contact metamorphism caused by early Sardic magmatism (perhaps represented by amphibo- lite and orthogneiss lenses in the metapelites). In the latter case, an anticlockwise compressional PT evolution (path 1 ...
I still can’t tell a schist from a gneiss, but I did find the books strangely reassuring. I actually also learned a bunch of stuff I didn’t know before. Like about how the planets moved in their orbits as they formed. That the earth at some point had rotated north to south (...
Dhadkhola Gneiss and Sermanthang formations, where dominant lithology is quartzite and schist, are more susceptible to landslides in the study area. Landslide occurrences in the soil type-Eutric Cambisols and Regosols are higher. The Eutric Cambisols of the Temperate zone (part of study area is...
For example, spodumene ore deposit of pegmatite type can be hosted with basic rocks instead of granite, gneiss, schist and other common host rocks. The size of spodumene grain can be either coarse or fine in the pegmatite. The zonality of pegmatite veins containing spodumene can be of good...
The soils and landforms of the study area were derived from granitic gneiss material (Churchward et al. 1988). Landforms form a catena of well-drained ridge and hillslope units (named Collis and Lindesay, respectively) and poorly drained swampy slopes, plains, and drainage floors named Caldyanup...
Crystalline rocks, such as granite and gneiss, are mainly composed of different aluminosilicates and minor minerals. It is expected that most of the radionuclides in the water are cationic or neutral and have the potential for surface complexation and cation exchange with the negatively charged surfa...

Nevertheless it could be observed how the two brittle fault sets intersect each other at an angle of 25° to form a conjugate fault system. WNW-ESE striking fault zones are statistically minor but can be clearly seen in aerial photos of the Fibbia-granitic-gneiss (Fig. 5) and through ...
It can also be found in metamorphic rocks, particularly in those that have undergone regional metamorphism, such as schist and gneiss. Group 3-green is the second largest, containing elements such as Cu, Pd, Ag, Os, Au, Ir, Pt, Pb, and others. Minerals formed by these elements and S ...
This is how the two-way coupling of lithosphere and surface processes is implemented. In our fully coupled lithosphere and surface processes models, while interactions between erosion, tectonics, and climate form, modify, or destroy geomorphic features, the transfer of mass that results from erosion...
