Group-I kimberlites are of CO 2-rich ultramafic potassic igneous rocks dominated by primary forsteritic olivine and carbonate minerals, with a trace-mineral assemblage of magnesian ilmenite, chromium pyrope, almandine-pyrope, chromium diopside (in some cases subcalcic), phlogopite, enstatite and of Ti-poor chromite. Group I kimberlites exhibit ...
Distinctive multi-coloured central face of the Contrafort de Rumbau; the climber is on Joe Blau 8c+ (5.14c); La Dura Dura is far left. The most technically difficult part is the first 10-metre section, which Ondra and Sharma described as "really bouldery" with 15 moves that would constitute a 9b/b+ climb on their own. [8]
Monolith with bull, fox, and crane in low relief at Göbekli Tepe. The density of most stone is between 2 and 3 tons per cubic meter. Basalt weighs about 2.8 to 3.0 tons per cubic meter; granite averages about 2.75 metric tons per cubic meter; limestone, 2.7 metric tons per cubic meter; sandstone or marble, 2.5 tons per cubic meter.

Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these ...
Granite (/ ˈ ɡ r æ n ɪ t / GRAN-it) is a coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
Silence (also Project Hard), is a 45-metre (148 ft) severely overhanging sport climbing route in the granite Hanshelleren Cave in Flatanger Municipality, Norway.When Czech climber Adam Ondra made the first free ascent on 3 September 2017, it became the first rock climb in the world to have a proposed climbing grade of 9c (5.15d), and it is an important route in rock climbing history.
