Alteration and vein mineralisation within the Lizard complex, south Cornwall: Constraints on the timing of serpentinisation. [PDF]
Two distinct episodes of serpentinisation have been identified within the peridotites of the Lizard complex. The first episode (primary serpentinisation) is represented by the complex and pervasive hydration of the Lizard peridotite.

Petrologic-geochemical evidence of geologic-genetic uniformity of gold hydrothermal deposits formed in black-shale and non-shale substratum [PDF]
The problem of gold deposits origin lying in crystal and black-shale substratum is discussed. The expediency of comparative research of all geologic-real-genetic factors of their formation, among which a significant value is retained by the geochemical ...

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.
