Lamprophyre is widely distributed in the Qinling area. Most of the lamprophyre alteration-type gold deposits are discovered in both sides of the Huixian-Chenxian basin. The study of gold preconcentration by lamprophyre dyke has been made. Therefore it is hopeful to expand the gold prospects by further studying the gold preconcentration and mineralization features of the altered lamprophyre type of gold deposits in the Qinling area.
