Abstract:
The Nenjiang Formation Members 1+2 (K2n1+2), which formed during the Late Cretaceous in the Songliao Basin, is a lacustrine mudstone deposition, on which abundant terrestrial paleoclimate information is preserved. This study examined mineralogy, as w...

Abstract:
Ninety samples from nineteen sites in the Songnen Sandy Land, along with eight L1 loess deposit samples from the Harbin Tianheng mountain, were separated into different grain size fractions (<63 μm, 63⁃30 μm, 30⁃10 μm, <10 μm and <30 μm) and 124 acid...

Abstract:
Through detailed field investigation of the loess area on the western side of Liupan Mountains, a loess paleosol profile with a thickness of 3 m was found on the flat ground of the third⁃level terrace of the Shuiluo River in northern Zhuanglang count...

Abstract:
Volcanism is a phenomenon in which lava (magma), pyroclastics and volcanic gases are ejected through a vent to the surface of the earth. Volcanic eruptions may inject large amounts of pyroclastics and Volcanic gases into the atmosphere and into marin...
