INTRODUCTION
The global distribution of mineral deposits on the Earth shows that some areas concentrate large resources (with high endowment), whereas others are almost devoid of any resource. This has led [1] to introduce for the first time the term "metallogenic province". The first definition of a uranium province was proposed by [2]: “Economic uranium deposits resulted from original...

INTRODUCTION
Uranium deposits in continental blocks of the Earth are distributed rather randomly and form uranium provinces and districts. Under the uranium ore province we mean crust block characterized by occurrence of uranium deposits of a certain type (or types), main features of which are resulted from specific ore-forming processes and peculiar geotectonic position. When...

INTRODUCTION
Sodium metasomatites are relatively widely distributed in the world and often contain uranium mineralization that occasionally may reach industrial scale [4]. Uranium concentrations in deposits of this type are rather low but resources can be quite large especially in the areas where sodium metasomatites achieve wide distribution. As was pointed out by [4], deposits of this...

Soils and rocks have a complex matrix composition and their contained-element chemical analysis is interested in geochemical and environmental studies. A well-established and commonly technique to obtain chemical composition in geological sample is X-ray fluorescence (XRF) spectroscopy [1]. The XRF technique has been used to eliminate matrix effects and sample heterogeneity...

ABSTRACT
In the Xiazhuang and Zhuguang uranium ore fields of the Nanling Metallogenic Belt, southeast China, granite-related hydrothermal uranium deposits formed in two major mineralisation stages: (i) an early Yanshanian high-temperature stage (175–145 Ma) concomitant with the early Yanshanian magmatic event; and (ii) a late Yanshanian low-temperature stage (110–50 Ma) that occurred during...

Interest in rare earth minerals (REE) originated in 1883 with the development of incandescent gas mantles containing rare earth and zirconium oxides. The knowledge that the supply of REE will not be able to keep up with new and ever-growing demands has been no secret in the geological community for years. However, it was not until it was presented to congress as a “potential...

The semiarid Southern High Plains (SHP) physiographic region hosts calcrete uranium deposits in Pliocene and Pleistocene sediments. This region was identified by the U.S. Geological Survey (USGS) as prospective for calcrete uranium deposits, although no deposits of this type had been identified in the US. The existence of deposits in the area was confirmed through historic exploration reports...

HISTORICAL BACKGROUND
In 1995, the International Atomic Energy Agency published a map, World Distribution of Uranium Deposits followed in 1996 with a World Guidebook [1] to accompany the map. The guidebook contained information for 582 uranium deposits (≥ 500 tU, ≥ 0.03% U), describing 13 parameters that included location, status, resource range, average grade range, age, host rock and...

The Streltsovka collapse caldera hosts the largest U ore field associated with volcanism in the world. Its total ore resource of more than 250,000 tU is distributed in 19 deposits. The dominant hypotheses of the origin of these Mo-U deposits, as proposed by exploration geologists, suggest that uranium was transported to the sites of ore deposition by ascending flow of magmatic...

1. Introduction
The Neogene-Quaternary collision of the African, Arabian and Indian plates from the south and the Mesozoic-Cenozoic subduction of the Pacific plate from the east led to the formation of large orogenic belts in the regional parts of the Eurasian plate. Each of them is characterized by its metallogenic peculiarities. The analysis of spatial distribution of endogenous and...

The IAEA has produced several volumes focussed on uranium deposit types that were the result of several expert-led working groups. In the last 25+ years, since these volumes have been published, there has been considerable research and advances in the understanding of uranium deposits, particularly for unconformity type deposits. Up until 2009, the world’s largest share of production came from...

It is generally accepted that the ore-forming fluids in unconformity-related uranium deposits of the Athabasca Basin in northern Saskatchewan were derived from evaporitic seawater in the basin. However, it remains controversial whether uranium was extracted from the basin sediments or from basement rocks. It has been argued that oxidizing conditions and availability of fluid in the basin were...
