Abstract

The diabasic dykes exposed at the Trai Mat quarry, Da Lat city intrude the granitoids of Ankroet complex (such as middle – coarse grained biotite granite and leucogranites. As can be seen in the field the thickess of these dykes vary from 0.5m to nearly 1.5 m extended north-south-east slope angles ranging from ~50 0 to being upright (Orientation of lying 31<50 ÷ 90 o). Petographical components consist of diabaz porphyrite. The main mineral components are plagioclase, pyroxene?, quartz, carbonate, chloride. Chemical components of rocks are: SiO2: 54.34 %, K2O: 2.43 %,Na2O: 2,50 %. The content of W, Pb, U, Th, Hf, Rb, Au is higher
