Synthesis Experimental Study on the Supporting Capacity of the Strongly Weathered Diorite in Jinan Area

, 2011
The strongly weathered rock zone is a special kind of rocks and soils mass. For its larger burial depth and low utilization of natural foundation, the physical and mechanical properties of the strongly weathered diorite were grasped poorly.

Unveiling the radiation shielding efficacy of diorite, granodiorite, tonalite, and granite: experimental and simulation study

For the purpose of this study, four natural rock samples-namely, diorite, granodiorite, tonalite, and granite-are being investigated about their radiation attenuation.

Reflection of petrologic regularities in the mineralogy of tonalite-granites and diorite inclusions in them: Comparison of granitoid massifs of the Urals and the Alps

Vestnik MGTU
Orogenic granitoid massifs contain a variety of mafic inclusions (autoliths, xenoliths, mingling dikes). These include predominantly diorite-series inclusions, which visually contrast with the host tonalite-granite associations but have similar mineral ...

The Val Biandino Intrusive Suite (central Southern Alps, N Italy): new geochronological and geochemical data on the Early Permian magmatic activity in the Southalpine Domain

Swiss Journal of Geosciences
The Early Permian in the present-day Europe area was a time when a major tectonic shift occurred, leading from the tectonic collapse of the Variscan orogeny to the crustal extension and thinning that characterized the Early Permian times.

Paleomagnetic studies of bulk mineral separates from the Bark Lake diorite, Ontario

, 1979
The separation of superimposed stable remanent magnetizations, increasingly a problem in the study of paleomagnetism of metamorphosed terrains, has usually been attempted using indirect techniques such as vector subtraction.
