Sanjiang and Jiaodong areas are the important gold regions in China.The gold mineralization is correlated with the Mesozoic faults and its derivative faults in the granite or the contact zone between granite and base rock.The mineral mapping is one of the important approaches of prospecting mineralogy.The temporal and spatial band distribution of mineral,mineral combination and mineral typomorphism features are natural regularity rules,but this kind of band feature is sometimes hidden and thus in need of mineral typomorphism research and mapping to disclose this band feature and to serve for the prospecting of mineral.The changes of the mineral typomorphism feature are often embodied in the"through"mineral,the typomorphism features of the through mineral change like the gradient toward the ore body,and the changes of the features are most obvious and strongest toward the orebodies.The new American mineralogy mapping indicates the weak change of the mineral composition or structure will lead to the change of the shape and wave length position of the specific absorbent feature.Australian experiment lab investigation has held the reason of a series of mineral.The progress achievement of the remote sensing and computer analysis technology now permits a direct comparison directly between the lab and remote sensing data,so the good feature database of the experiment light spectroscopy can serve for drawing of the spacial distribution and remote sensing material.Mineralogy mapping raised the extensive emphasis in the international earth arena.
Sanjiang and Jiaodong areas are the important gold regions in China. The gold mineralization is cor- related with the Mesozoic faults and its derivative faults in the granite or the contact zone between granite and base rock. The mineral mapping is one of the important approaches of prospecting mineralogy. The temporal and spatial band distribution of mineral, mineral combination and mineral typomorphism features are natural regularity rules, but this kind of band feature is sometimes hidden and thus in need of mineral typomorphism re- search and mapping to disclose this band feature and to serve for the prospecting of mineral. The changes of the mineral typomorphism feature are often embodied in the ＂ through＂ mineral, the typomorphism features of the through mineral change like the gradient toward the ore body, and the changes of the features are most obvious and strongest toward the orebodies. The new American mineralogy mapping indicates the weak change of the mineral composition or structure will lead to the change of the shape and wave length position of the specific ab- sorbent feature. Australian experiment lab investigation has held the reason of a series of mineral. The progress achievement of the remote sensing and computer analysis technology now permits a direct comparison directly between the lab and remote sensing data, so the good feature database of the experiment light spectroscopy can serve for drawing of the spacial distribution and remote sensing material. Mineralogy mapping raised the exten- sive emphasis in the international earth arena.
