The Problems of Tin Metallogeny

1988
On the basis of the spatial and temporal distribution of tin deposits in the world and their relation to different kinds of igneous rocks, the sources of tin are discussed according to the available tin abundance in meteorites and ultramafic, mafic and felsic rocks in combination with the siderophile habit of tin.

Sulfur in the precambrian metallogeny

Geologische Rundschau, 1973
The economically important sulfide deposits of Precambrian age can be subdivided into two principal groups. The first group is represented by Ni- and Cu-bearing differentiates within either layered intrusions of the Sudbury-Bushveld type or within smaller ultramafic bodies (sometimes of greenstone belt association).

Metallogeny of the Rapakivi granites

Mineralogy and Petrology, 1995
Two major types of ore deposits occur with Proterozoic rapakivi granite plutons: (1) greisen-, vein-, und skarn-type Sn(-W-Be-Zn-Cu-Pb) deposits associated with specialized late-stage granites, and (2) Fe oxide-Cu (-U-Au-Ag) deposits.

The Metallogeny of the British Isles

Quarterly Journal of the Geological Society of London, 1910
I. I ntroduction . T he recent development of the geographical method of studying ore-deposits is due to Prof. L. de Launay, who first pointed out its application in 1897. His later works on this plan include examinations of the ore-deposits of Africa, Italy,
