Studies of the Precambrian Geology of Iowa: Part 3. Geochronologic data for the Matlock drill holes

Studies of the Precambrian Geology of Iowa: Part 1. The Otter Creek Layered Igneous Complex

Forward Modelling Surface Nmr for Hydogeological Applications in Australia

INTRODUCTION Groundwater plays an important part in many regolith processes (chemical weathering, solute dispersion, etc.), but collecting groundwater data usually requires drilling that can be: a) expensive analyses for porosity, permeability, etc in addition to drilling costs; b) problematic rig availability and access to remote sites; c) under-sampled entire groundwater regimes characterised...

A comparison between geochemistry of metapelites of Hindoli and Jahazpur Groups: Two Precambrian low-grade metasedimentary sequences in NW India

The Bundelkhand-Aravalli craton is the most important lithotectonic unit in the central and western India where Paleoproterozoic Aravalli Supracrustal sequence has been deposited over an Archaean basement, the latter also known as the Banded Gneiss Complex (BGC). A NE-trending linear metasedimentary sequence, designated as the Jahazpur Belt occurs along the eastern fringe of the Aravalli Superg...

Assessment of an ore body internal dilution based on multivariate geostatistical simulation using exploratory drill hole data

Dilution can best be defined as the proportion of waste tonnage to the total weight of ore and waste in each block. Predicting the internal dilution based on geological boundaries of waste and ore in each block can help engineers to develop more reliable long-term planning designs in mining activities. This paper presents a method to calculate the geological internal dilution in each block and ...

Geological Structures That Have Control on Groundwater Occurrence of Chamarajanagar Taluk, Chamarajanagar District, Southern Karnataka

Geology of this area is ranging from Precambrian age for the rocks of granite, gneisses, schist and quartzite rocks, to recent age overlain by thick layers of alluvial deposits. This study aims to evaluate geological and structural influences on groundwater of Chamarajanagar taluk. It is an essential resource in outcrop and structures of the area, because of local field conditions, such as rock...
