However, there is still a lack of a dataset on rock properties, especially the abrasivity of various rocks. This paper reports the abrasive dataset of 10 kinds of rocks, including sedimentary rocks, metamorphic rocks, and igneous rocks, with the aid of the CERCHAR Abrasivity Test and digital...
However, all that is known for sure abouthow this mineral is formedis that the circumstances are unique. It was uncovered as a waterworn crystal in alluvium, and based on its composition, researchers believe it originated in pegmatite. Suchigneous rocks are created during the last stage of cr...
There are various types of pollution i.e. air, water, land, noise, industrial, soil, light, thermal etc. and they are categorized based on the region of the environment which they negatively impact, contributing to the multiple causes of pollution. Accordingly, each and every type of pollutio...
touch, a few simple tools and extensive knowledge of rocks, minerals and rock formation to identify different rock layers. Rocks are classified into three main types, sedimentary, igneous and metamorphic, based
Salt weathering is a type of physical weathering existing almost everywhere on the world land,damaging surface of rocks and building stones,forming geomorphological sceneries,such as tafoni or honeycomb structures because of the periodical salt crystal growth. Salt weathering is also one of the major ...
GEOCHEMICAL COMPARISON OF METAIGNEOUS ROCKS IN THE ADIRONDACK HIGHLANDS AND LOWLANDS: DIFFERENT ROCKS, DIFFERENT TERRANESThe Northwest Lowlands, with a higher proportion of metasedimentary rocks suggestive of affinity with the Frontenac terrane, contain at least six distinct groups of granitoids (Antwerp...
Silica-undersaturated potassium-rich igneous rocks and their derivants were earlier considered to be a rare group of rocks occurring in widely scattered localities all over the world (Turner and Verhoogen 1960). During the last three decades however, a large number of localities have been ...
A critical study on the type of the magnetic grains, both in composition and domain state, in rocks of different ages has been carried out. One simple, fast and non-destructive test, which can provide useful information on the nature of the magnetic grains in freshly collected samples, seems...
The UCS losses in the vast majority of rocks fall in the range from 0% to 60%. Compared to metamorphic and igneous rocks, sedimentary rocks generally suffer greater reductions in UCS. However, rock strength is susceptible to the test conditions [7,24,31,32] such as strain rate, loading ...
How landslide-triggering rainfall conditions vary with geology is unclear. The effects of three different geological conditions (gneiss, GN; granite, GR; sedimentary rock, SR) on variations in intensity–duration (I-D) conditions and rainfall characteris
