文摘The living circumstances of human beings are closely related to the geological environment. As exemplified by the Zhangjiakou-West Beijing region, this paper describes the intensive mantle-crust uplift, which led to anomalous element background values for regional rocks (ores) and soils. As a result, some agricultural crops, and forests and fruits are of “super-quality and high yield” or of “poor quality and low yield”. The anomalous elements can find their way into grains, fruits, vegetables and drinking water and then will be taken by human beings, constituting a food chain, which would directly impact human health and lead to the spread of some endemic diseases. Studies have shown that the geomorphological features in the Zhangjiakou-West Beijing region are the outcome of geotectonic evolution since the Mesozoic. Mantle-crust movement is the key factor leading to the evolution and change of the regionally geological environment.
