DEMONSTRATION PHOTOGALLERY


It is recommended that you view Data Metallogenica photogalleries using Microsoft Internet Exlorer Version 5.5 or higher, and a screen resolution of 1024 x 768. Click on any thumbnail to view the image at full size. This gallery contains several types of data from more than one deposit which is not normally the case. In practice, galleries are specific to deposit and data type (eg plan, field, measurement), and introduced by a description: an example of which follows for Las Cruces:-

The Las Cruces copper deposit is located 20 km northwest of Seville, in the Autonomous Region of Andalusia, Spain. It is concealed under a cover of approximately 160 m of sediments and was discovered in 1994 by the use of gravity surveying. The current (2003) owners,MK Gold Company, plan open pit mining, leaching of ore, and production of cathode copper for sale to the European market. The deposit is probably early Carboniferous in age (~350 million Ma). Host rocks are volcanic tuffs and black shales with mineralisation having the typical Iberian Pyrite Belt characteristics of:- (1) massive base metal sulphides with trace silver and gold; (2) pyrite stockwork beneath massive mineralisation; (3) deformation, faulting, and extensive chlorite-sericite alteration; (4)metal zonation (Cu-rich and Zn+Pb-rich parts). In addition, uplift, weathering, and partial exposure have created a high grade supergene copper zone near the top of the orebody which includes gossan, precious metal concentration, and silicification of thehanging wall. The main Massive Sulphide (MS) unit is up to 100m thick, strikes broadly E-W over >1km and is thickest to the west.
