I grew up in South Africa in the mining town of Phalaborwa and later in Cerro de Pasco, Peru.  It was in Peru at a young age that I developed an interest in minerals and geology and have been collecting minerals ever since.With a collection of over 3000 specimens, my area of interest is in the minerals of the Kalahari Manganese Field, the Phalaborwa Carbonatite, Nambia and in general southern African minerals including the rather obscure minerals of the late Bushveld Igneous events such as the Vergenoeg Fluorite deposit. I have a special interest in the minerals of Peru, especially its sulphides. I have had many opportunities to collect minerals at Vergenoeg mine and several other South African localities including the Pering Mine and Nchwaning II Mine.  I enjoy the tactile immediacy of collecting minerals and consider it to be the most enjoyable of hobbies. I am also very interested in geology with my main areas of interest in the rocks of Archean age, the origin of the Earth and the enigmatic processes leading to the origin of Life on Earth.  Other interests include meteorite impacts and their relation to extinction events (the Cretaceous-Tertiary extinction event in particular) and the geology of Mars and the Moon. I have a sceptical disposition and believe in questioning the validity of claims by following basic scientific methods of observation, independent testing, rational deduction, and verification by means of abundant evidence. I fight the misuse of science and praise the real wonder of science.    I am past chairperson of the Witwatersrand Gem and Mineral Club and currently the editor of the South African Lapidary magazine.  I hold a National Diploma in Analytical Chemistry, and am registered as a Professional Natural Scientist with the South African Council for Natural Scientific Professions, a member of the South African Chemical Institute and an affiliate member of the Geological Society of South Africa and a member of the Mineralogical Society of America.    I am a consulting analytical chemist and owner of Allan Fraser and Associates, a consultancy services company specialising in education and training of laboratory analysts and laboratory audits. http://www.allanfraserandassociates.co.za/     In 2001 I became a hobby mineral dealer and started www.onlineminerals.com. My web site offers mineral specimens mainly from southern Africa and minerals from some international localities. Over the last year the focus of the web site has changed to include more specimens from Namibia and the Kalahari Manganese Field. I also buy and evaluate mineral collections, so please contact me if you are interested in selling or simply having your collection valued for which I will charge a nominal rate.  I hope that you enjoy my web site and stop to visit it from time to time.  If you feel I could improve the site in any way please let me know. If there are any particular minerals you wish me to search for I will do my best in sourcing them for you. I have an extensive network of dealers, miners and collectors.  You can email me at mineralman@telkomsa.net or info@onlineminerals.com   Below is a collection of photographs of various collecting expeditions, mineral shows, fellow mineral collecting enthusiasts and an assortment of intriguing geology. I have added a few of my favourite specimens from my own collection (sorry, they are not for sale), from various sites.   For a more complete biography and my mineral label archive visit the Mineralogical Record at this link: http://www.minrec.org/labels.asp?colid=1309   Visit my blog at http://www.iridiumminer.blogspot.com/ A blog site for anyone interested in the Sciences and rational thinking.     (Disclaimer: The locality information on this web site is for reference purposes only.
