S. S. Goldich derived this series in 1938 after studying soil profiles and their parent rocks. [1] Based on sample analysis from a series of weathered localities, Goldich determined that the weathering rate of minerals is controlled at least in part by the order in which they crystallize from a melt.

A few days later, a hole as wide as 15 ft (4.6 m) and several feet high was found in the base of the north wall of the pit. Garbage had concealed the hole and prevented it from being filled with non-combustible material. It is possible that this hole led to the mine fire, as it provided a pathway to the labyrinth of old mines under the borough.
Maryland Route 6 (MD 6) (sometimes called Port Tobacco Road) is a state highway in the U.S. state of Maryland. The state highway runs 47.36 miles (76.22 km) from a dead end at the Potomac River in Riverside east to MD 235 in Oraville .
Seatearths have also been called seat earth, "seat rock", or "seat stone" in the geologic literature. Depending on its physical characteristics, a number of different names, such as underclay , fireclay, flint clay , and ganister, can be applied to a specific seatearth.
Alkali feldspar granite, some varieties of which are called 'red granite', [1] is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals. [2] [3]
White veins in dark rock at Imperia, Italy. In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock.Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation.
