About J.M.W. Geo-Consulting
J.M.W. Geo-Consulting was set up by Dr. J.M. Warnsloh in January 2009 to deliver services in mineral exploration and petrography. Back then, the core business was consultancy in the fields of economic geology and natural stone analysis. Over the years, the activities broadened from general services during exploration projects over pollution and air quality assessments in buildings and at workplaces to data analytics in different fields (geo-scientific and beyond).
About J.M. Warnsloh
I am a graduate mineralogist with 25+ years experience in petrology, economic geology, air quality assessments and data analytics. I hold an M.Sc. in economic geology and geochemistry (Department of Mineral Resources, Clausthal University of Technology) and a doctorate degree in applied geochemistry (Institute of Mineralogy and Economic Geology, RWTH Aachen University).
I accomplished projects in economic geology (focus on niobium and tantalum mineralization), mineralogy for mining and process metallurgy companies, petrographic examinations of natural stones, as well as mineral exploration campaigns. Furthermore, I have demonstrated skills in drilling supervision, core logging and quality control and gained a high expertise in the field of niobium mineralization and carbonatite-hosted commodities (e.g. Niobium, REE), salt and quartz.
Besides this, I got trained in air quality assessments and management and used this skills consulting other companies and to train companies and individuals operating air quality monitors.
In all projects, I have to use methods of data mining, data modelling and data visualization, which has led me to further my education and training in this field of work.
During my years as a researcher (1999 – 2009) I worked with radioactive minerals and as head of an X-ray laboratory (2005 – 2009) I was responsible for the radiation safety of my employees.
In roles as economic geologist, I frequently came into contact with (fine) dust pollution in mines during exploration projects in the mining industry, which sparked my interest in air quality and its studies in association with workplace pollution.
Since 2013, I have been continuously educating myself by attending various courses at internationally renowned institutions in the field of air quality.
Here, my educational paths and training are split in my main working fields:
