Geophysics in Gold Exploration: Application to Greenstone Belt Gold Deposits

3rd International Congress of the Brazilian Geophysical Society, 1993
The use of geophysical methods in exploration for greenstone belt gold deposits is as an indirect tool. These methods assist the exploration effort by mapping structures, lithologies, and alteration effects that may be related to mineralization. By using deposit models, and with knowledge of the deposit characteristics that are important for providing ...

Application of placer gold morphology to gold exploration

2017
Placer gold undoubtedly carries some of the features of endogenous gold. The physical and chemical characteristics of such gold are influenced by many factors: the nature of the primary gold, the water force, the morphology of the river bed, the length of transport and the chemical composition of the water in the river. In the Republic of Macedonia has

Exploration for Epithermal Gold Deposits

2000
The successful exploration geologist uses knowledge of geologic relationships and ore-deposit styles, tempered by experience, to interpret all information available from a given prospect in order to develop an understanding of its mineral potential.

Geochemical exploration for gold in glaciated terrain

1991
In regions that were glaciated in the Quaternary, mineral exploration can be hampered by the complexity of the surficial sediments, which are largely allochthonous in relation to the bedrock they overlie. In the context of almost totally glaciated landscapes, which includes most of North America north of 40°N, Greenland and Iceland, most of Europe ...

Using plants as an exploration tool for gold

Journal of Geochemical Exploration, 1989
Abstract Creosote bush (Larrea tridentata), burr bush (Franseria dumosa or Ambrosia dumosa), and sagebrush (Artemesia californica) have been tested for Au biogeochemically in the arid environment of the Mojave Desert on the Standard Hill property, which is located approximately 100 km from Los Angeles, California.

Conceptual models in gold exploration

2005
Process-based conceptual models for gold exploration are replacing empirical based conceptual models. Comparison of both types of targeting shows process modelling to be more predictive, fewer and more accurate targets.
