Late Precambrian algal megafossils Chuaria and Tawuia in

In the latter, Chuaria is associated with the genus Tawuia which Hofmann (in Hofmann & Aitken, 1979) described as algae of undertermined affinity and which is based on material from Canada. The glauconitic sandstone directly resting upon Chuariabearing greyishgreen shale of the Jingeryu Formation in Jixian County has a KAr age of 0.899 Ga.

Characteristics of geothermal reservoirs in the Wumishan

In the supratidal zone, the lithology is dominated by thin layer of grey dolomite or greygreen dolomitic shale. The depositional environment changed to lagoon in the middle part, of which the lithology is characterized by interbed of greygreen shale and shallow grey fine crystalline algal dolomite.

Creep on the Rodgers Creek fault, northern San Francisco

Abstract [1] Deformation in the northern San Francisco Bay area is dominated by a series of subparallel strikeslip faults. Existing GPS observations provide some constraint on the slip rates of these faults, however these have only limited resolution for resolving shallow fault behavior, such as brittle creep.

Named "plumbago" in 1739 by Magnus von Bromell, but in a different sense than previous authors such as Agricola and Conrad Gesner. Also called "molybdaena" but "molybdaena" was shown to represent two species, molybdenite and graphite as known today, in 1781 by Carl Wilhelm Scheele. Named graphite in 1789 by Abraham Gottlob Werner from the Greek "graphein" "to write".
