Radiogenic Heating as the Thermal Driver of Himalayan Crustal Heating During Prolonged Thickening
Abstract The thermal evolution of the crust during continental collision evolves from cold to hot with time, which impacts crustal reworking and differentiation. However, it remains elusive as to the mechanism driving the crust to be hot during the protracted collision.

Sulfur isotope composition in the Plesenci native sulfur mineral deposit, Republic of Macedonia [PDF]
For the first time, we present our findings of the origin of sulfur in the gypsum and native sulfur within the Plesenci deposit, R.Macedonia. There we made a series of complex research and analysis of the light isotope (32S), heavy isotope (34S), and ...

Linking Archaean climate change with gold metallogeny
First large-scale concentration of gold to ore grade in Earth’s crust took place at around 2.9 Ga in quartz-pebble conglomerates, well before endogenous deposits, such as porphyry and epithermal systems or orogenic-type deposits, started to play a ...

Implications of Northwest Pacific Ocean Eolian Records for Northern Hemisphere Wind System Evolution
Abstract Northwest Pacific Ocean sedimentary eolian records preserve abundant information about the temporal evolution of Northern Hemisphere atmospheric circulation. The large spatial scale of these wind systems means that they play key roles in driving dust transportation from inland areas to the open ocean. However, the altitudinal range of dominant

Bipolar Seesaw of Atmospheric CO2 Between North Pacific and Southern Ocean at Millennial Timescales
Abstract The interhemispheric relation of deep‐water ventilation and surface‐ocean productivity may have played a prominent role in past atmospheric CO2 regulation. However, how these processes vary on orbital‐millennial timescales remains poorly understood.

Ore bearing factors of breaking-block structures of the Ukrainian shield
Most ore occurrences and mineral deposits are known to be located in tectonic fault zones. In this regard, the article analyzes the ore content of regional and local fault zones developed in the megastructures of the Ukrainian shield: Podolsky, Volynsky,
