Leach definition, to dissolve out soluble constituents from (ashes, soil, etc.) by percolation. See more. As the author states, it is an attempt to improve upon the seminal early books on leach capping interpretations led by Blanchard (), who produced the bible on leached cap interpretation.
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features. Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by a mantle of soil and vegetation and cannot be seen or examined closely.

The leached element concentrations of CS, originating from India (3 samples), Singapore (6 samples) and Chile, Canada and the United States (11 samples in total), obtained using the TCLP test and published since , are given in Table The US EPA regulatory levels for metals that are characterised as hazardous are also listed in the same table (US EPA, ). Abstract. With the rapid growth and development in the fields of applied geochemistry and geophysics there is a tendency to underestimate the importance of geological mapping and prospecting in Author: J. H.

Books, images, historic newspapers, maps, archives and more. Leached capping over disseminated (porphyry copper) deposits is more favorable than gossan from massive sulfide deposits for the interpretation of leached outcrops.
Subsidence features related to collapse of gossan derived from massive sulfide ore bodies may provide excellent guides for exploration. This text concentrates upon field observations concerning leached cappings and gossans, occurring as oxidised surface expressions of underlying ore zones.
Although the advent of modern multielement geochemical sampling and easier mechanical excavation assist considerably in subsurface interpretation, there are still many occasions where the.

Leached Outcrops The interpretation of gossans and leached cappings is one of the earliest recognized guide to ore and led to the discovery of many of the important mining districts of the world.
The study and interpretation of capping by Asarco geologists in the mid th century led to the onset of bulk, low-grade mining of oxidized copper ores, dominated by chalcocite, and the utilization of SEDEX technology since the late s has led to the leaching processes used currently.
The Cornish term gossan is applied to chemically weathered, iron-stained outcrops of sulfide mineral deposits. Synonyms include the French chapeau de fer, the German eiserner Hut, and the Spanish colorados. The term pacos ore is used in Bolivia for gossans over tin veins that are residually enriched in workers reserve the term “capping” for gossans over disseminated.
