The origin of coal and groundwater circulation in Northeast China.

The dataset contains hydrogen and oxygen isotope data of different water bodies in the Northeast China. Cr and Ni elements contents of coals in different areas of the world were collected. Hydrogen and oxygen helps to determine the groundwater source of the Changbaishan Mountains. He and Sr isotope is used to analysis the depth and transport of groundwater. Because the Siderophile elements in the coal seam should have come from the hydrothermal during the coal-forming period, Cr and Ni elements can help to analysis the hydrothermal origin.
