秘鲁Don Javier斑岩型铜钼矿床矿化蚀变特征及矿床三维勘查模型
Alteration-mineralization characteristics and three-dimensional exploration model of Don Javier porphyry copper-molybdenum deposit, Peru
摘要
Abstract
The Don Javier copper deposit is located in the northern part of the Paleogene porphyry copper-molybdenum metallogenic belt in the south of Peru.It is one of the newly discovered porphyry copper-molybdenum deposits in this metallogenic belt.The copper resource is 1.29 million tons with an average grade of 0.43 %,the associated molybdenum is 52 300 tons with an average grade of 0.017% and 800.56 tons of silver with an average grade of 2.64 g/t.In order to increase the metal resources and satisfy the demand of the follow-up assessment and development of the mine,this paper helps the readers to determine the location of new prospcctivc arcas around the deposit based on studying the geological characteristics and metallogenic regularity of the deposit.By studying the geological condition of mineralization,the mineralization-alteration features and the three-dimensional distribution pattern of the deposit,the authors hold that the main orebody is hosted in the phyllic altered dacite porphyry.By establishing the three-dimensional geological model of the deposit and combining the geophysical and geochemical prospecting results,the authors have reached the conclusion that there exist prospecting potential in the northeastern and the southeastern part of the orebody.关键词
