Values of the blasting coefficient can be 9 to 15 for quartzite, between 10 and 17 for most igneous rocks like granite and basalt, and range from 17 to 23 for sedimentary rocks such as limestone (USACE 1972). The blasting coefficient is a good indicator of the degree of spalling, with a higher number indicating greater spalling in the rock.

Naturally formed geologic melts abound, in their cooled form as igneous rocks such as basalt. Remelting of rocks, and subsequent controlled cooling for forming a solid with desired properties, is a relatively recent concept. For example, the recorded history of melting basalt rock and manufacturing glass fiber from the melt dates back to 1922 ...

Tribal members mine the peridot, which occurs as small green grains in the basalt. The entire volcanic structure called Peridot Mesa is mined exclusively by local residents. Peridot does occur elsewhere in Arizona, but the San Carlos Apache Indian Reservation is the leading source for peridot sold as rough and finished gems worldwide.

Mining is a skill that allows players to obtain ores and gems from rocks. The higher a player's Mining level is the more likely they are to successfully extract ore. With ores, a player can then either smelt bars and make equipment using the Smithing skill or sell them for profit. Mining areas are identified with a regular pickaxe icon, and mining shops are identified with a gold pickaxe …

rocks similar to the typical rocks listed in table 19-1. Denser rocks such as basalt require smaller ratios (higher powder factors). Lighter materials such as some sandstone or bituminous coal can be blasted with higher ratios (lower powder factors). The hardness or brittleness of rock can have a significant effect on blasting results.
