前言拉普拉塔铜矿床位于科罗拉多西南部的拉普拉塔山脉,海拔高度为3000-3850米。该矿床已有100多年的历史。在最近的30年里,有四家采矿公司对其进行过勘探。概述该矿床主要赋存于正长岩中。正长岩侵入至由页岩和砂岩及少量灰岩组成的古生代至中生代沉积岩层中。现已发现10条矿化带,但仅有阿勒德带被钻探过。阿勒德带地表有800米长,最大宽度为300米.其暴露地表的垂直延伸长度为450米,钻探揭露了850米,总长为1300
Preface The La Plata copper deposit is located in the La Plata Range, southwest of Colorado, at an altitude of 3000-3850 meters. The deposit has been more than 100 years old. In the last 30 years, four mining companies have explored it. Summary The deposit mainly occurs in syenite. The syenite intrudes into Paleozoic to Mesozoic sedimentary formations consisting of shale and sandstone with small amounts of limestone. Ten mineralized zones have been discovered, but only the Allard zone has been drilled. The Allard belt has a surface of 800 meters long and a maximum width of 300 meters.The vertical extension of the exposed surface is 450 meters and the drilling reveals 850 meters and the total length is 1300
