Fertilizing Properties of Potassium Feldspar Altered Hydrothermally [PDF]

Communications in Soil Science and Plant Analysis, 2019
The material obtained through hydrothermal alteration of K-feldspar rock in alkaline conditions is a potential source of soluble potassium (K), but agronomic testing is needed to verify its capacity to supply K to crops. A (NH4)2SO4-based bioassay was used to test the capacity of the material to supply K to tomato plants (Lycopersicon esculentum Mill.)

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

The geochemistry of hydrothermal alteration at the Bakircay porphyry copper prospect, northern Turkey.

, 1980
Isotopic data for the Bakircay granodiorite porphyry, give a Late Eocene age for the development of the porphyry copper system. They suggest a close temporal and genetic relationship between igneous and hydrothermal activity, and indicate that magmatic ...
