Geochemical Characteristic Of 1:50000 Stream Sediment Survey,and Metallogenic Prognosis Of Yangchun Area,Guangdong Province

The study area of Guangdong Province in area,located in the southwest section of Qin-Hangmetallogenic belt,Wuchuan-Sihui fault middle southeast side,and Guangdong in the Yunkai block interchange,polymetallic metallogenic belt of Yangchun basin.It has good ore-forming geological conditions and great prospecting potential.Yangchun Yuexi basin as an important polymetallic ore in Guangdong province area,area of complex structure,resulting in magma intrusion of multiple stages,the formation of different types,different types of minerals in the surrounding rock under different conditions of endogenetic metallic deposits.In this paper,the geochemical measurements of 1:50000 sediments of Yangchun area,in the range of 1904km2,a total of 19 abnormal circle,the value of classification of A1 class 5,A2 class 2,B1 class 6,B2 class 2,B3 class 2,C2 class and C3 class of all 1.On 7 W,8 Au abnormal and 5 abnormal Cu were abnormal after the evaluation of the multi parameter comprehensive view,AS13,AS15,AS18,AS5,AS10 five anomalies are looking for better prospects for tungsten AS19 is abnormal,find the best prospects for gold.AS5 is looking for the best prospects for copper anomaly.In addition,AS15,AS14 also have to find gold,copper better prospects,AS18 to find gold copper,AS13 copper is also more favorable to find.The study area can be divided into 6 geochemical zones and 4 geochemical sub regions according to the paragenetic Association and spatial distribution characteristics of the elements.The relationship between the elements and the symbiotic relationship is also discussed.Through the study of abnormal parameters,Yangchun area total of single element anomalies in W,Bi,Mo,Sn,Ag,Au times,abnormal size(NAP value)from roughly ranked as W,Bi,Mo,Sn,Ag,Cu,Au,so the main prospecting in the study area the mineral should be tungsten,bismuth,molybdenum,tin,copper,gold and silver for the second,for the future prospecting direction.In the study area is divided into seven prospecting areas.There is a prospecting area of 4,B prospecting area 2,C prospecting area 1.For the region mineral prospecting reduces the prospecting targets and pointed out the prospecting direction,provides abundant information for mineral prospecting points.
