Advances in Mineralogy, including Ore mineralogy, Gemology and Geometallurgy

Dr. K. L. Pruseth


Dr. Jayshree Panjikar



Minerals and geochronology

K L Pruseth


Dewashish Upadhyay


1. Dr. K.L. Pruseth is an experimental petrologist working in the field of ore geology and sulfide phase equilibria. He considerable experience in EPMA analysis and CHIME dating.

2. Dr. D. Upadhyay is an expert in the field of isotope geology. His current interests are in the mineral micro-domain scale isotopic measurements and dating.

Geochronology; isotope; dating; laser; micro-beam

Dating has been an important tool for understanding geological events and processes. Advances in relevant instrumentations have made possible acquisition of geochronological information from micro-domains in minerals revealing the stages of their evolution through series of geological events. The cumulative geochronological information from various datable minerals is essential for comprehensive geological understanding. Chemical dating of monazite and isotopic dating of zircon are the most used techniques. However, suitable other minerals from more specific environments are also in use.

The symposium addresses all innovations and improvements in analytical protocols for minerals expected to be used as geochronometers.

Quantitative Mineralogy – Applications and Value in Geoscience Systems

Shaun Graham


Vishwanath Uppugunduri (India)

1. He is a leading specialist in automated and quantitative mineral analysis. His particular research focus is the development and application of quantitative mineralogy techniques into a wide variety of materials and geoscience applications. His key focus areas currently are understanding how the multi-scale data acquired from these technologies can be used to deepen our understandings of complex systems (i.e. mineralogy processing circuits, ore genesis and mineral exploration targeting). Throughout the last 5 years he has contributed over 30 abstracts to international conferences, contributed to multiple peer-reviewed publications and supervised a number of Masters and PhD students.

2. He is one of the leading Geomettlurgists in the country with experience of more than 35 years in the base metals, precious metals and ferrous metals fields in India and abroad having served as Head Of R&D of HZL (Vedanta), where he initiated a number of recovery improvement projects based on the inputs of quant minerology which has helped HZL to become a world leader with highest recoveries of Lead, Zinc, Silver.

quantitative mineralogy, mineralogy, applied mineralogy

At the very essence of any applied physical science is the generation of quantitative data that is used to characterize, understand and explain complex systems. The techniques used in this application therefore provide extensive value in quantification of mineralogy, textures and complex associations across a range of scales. These quantitative studies therefore enable us to understand the system is greater detail and scale our quantified observations from the nanometre all the way through to the kilometre scale.

This aim of this symposium is to provide a forum for researchers to share ideas, new techniques and technologies and applications of automated and quantitative mineralogy. Whilst these capabilities have in the past primarily been a technology utilized in the mining community for Geometallurgy and process mineralogy (which is still a core theme of the symposium). However, papers demonstrating other applications in petrological studies (igneous and metamorphic), sedimentology, oil and gas / digital rock physics, etc. are encouraged.
