The deposit is situated in southeastern New South Wales at Lat.35°04*S, Long.1A9°34*E. (Fig.l) The first phase of testing proved up a body of poljmietallic massive sulphides and an adjacent zone of dominantly copper ore. The massive sulphides body consisted of about 6.3 million tonnes of copper, lead and zinc ore (1.7% Cu: 5.5% Pb; 14.4% Zn) and was the main target for geophysical investigation. The copper ore zone contains about 3.7 million tonnes averaging about 1.9% Cu, 0.1%Pb, 0.5% Zn in a number of ore shoots both along strike from and below the massive sulphides. Subsequent drilling indicated several concealed bodies of massive sulphides, separate from the first discovered body but these are at depths of more than 200m and hence too deep to have influenced the geophysical investigations.  <...>

The Tropicana-Havana gold deposit is hosted by Archaean rocks that lie along the eastern margin of the Yilgarn Craton, Western Australia. The Mineral Resource for the project is 75.3 million tonnes grading 2.07 g/t for 5.01 Moz of gold. Gold mineralisation postdates peak granulite-facies metamorphism and formed from variably oxidised, higher temperature (>350˚C), silica-undersaturated fluids.

Intrusion-related gold systems (IRGS) are a newly-defined (1999) deposit classification (based mainly on well-studied deposits in Alaska and Yukon) that is already mired in confusion, nomenclature uncertainty and misapplication. Increasingly, gold deposits are mis-assigned an IRGS classification because: 1) the nomenclature of intrusion-related gold models has been rapidly evolving; 2) the characteristics of the classification are broadly defined to include a wide range of deposit types that overlap with other gold deposit types; and 3) granitoid intrusions are common features of orogenic belts and are an obvious fluid source for any proximal gold occurrence. 

The main aim of this book is to provide an introduction to the most relevant investigation methods and techniques that can be used to study karst hydrogeological systems, including modern approaches to interpreting and modelling the data obtained. Studying karst aquifers is not only scientifically challenging, but it is also important for humanity. Ford & Williams (1989) estimated that 25% of the world’s population drink water from such resources. Although this number is probably an over-estimate, karst groundwater constitutes a crucial freshwater resource for many countries, regions and cities around the world.

Количественная оценка минеральных ресурсов платины, палладия, золота, никеля и меди в неоткрытых месторождениях PGE в основных и ультраосновных расслоенных  интрузиях в Финляндии

Most of the known platinum group element (PGE) resources in Finland are in contact- and reef-type deposits in 2.45 Ga mafic-ultramafic layered intrusions. These intrusions also have the potential to contain the majority of possibly existing, yet undiscovered, PGE resources in Finland. The undiscovered Pt, Pd, Au, Ni, and Cu resources in contact- and reef-type deposits were estimated down to one kilometre depth using the three-part quantitative assessment method.

In recent years, there has been increasing interest from geoscientists in potassic igneous rocks. Academic geoscientists have been interested in their petrogenesis and their potential value in defining the tectonic setting of the terranes into which they were intruded, and exploration geoscientists have become increasingly interested in the association of these rocks with major epithermal gold and porphyry gold-copper deposits. Despite this current interest, there is no comprehensive textbook that deals with these aspects of potassic igneous rocks. 

The earliest people in the Front Range area left scant record. During the Pleistocene, the first migrations of Oriental people crossed the Bering land bridge and some eventually moved into Colorado. Cliffdwelling Pueblo cultures developed in southwestern Colorado about 2000 years ago, with more nomadic tribes like the Ute and Apache arriving in Colorado about 700 years ago (Brown, 1985).
