Even the Scotland series probably belongs to the Tertiary system, but owing to the want of characteristic fossils, it is impossible to determine with any degree of certainty the precise homotaxis of the several formations.
At many of the mines at Kalgoorlie, Western Australia, large quantities of ores of telluride of gold have been found in the lode formations.
The types of vegetation (tropical forests, sclerophyllous forest, temperate forests, tundra, &c.) thus briefly outlined are groups of Schimpers climatic formations.
The geological formation includes (like that of Java) three regions - the central volcanic, the southern peninsula of Tertiary limestone, and alluvial plains between the older formations.
The fossils are few, and in some cases probably derived from the underlying formations.
