I am a 59 years old (b. 1960) Norwegian amateur mineralogist and a passionate mineral collector. By profession I am a theologian (missiologist). The world of minerals has fascinated me since I was 13. I am fortunate to live in the famous alkaline Larvik plutonic complex area (the Langesundsfjorden area) in the southeastern part of Norway. Also for 11 years, back in the 1990s, I also had my home in the marvellous country of Madagascar. My collection has thus its concentration by number of specimens from those 2 areas. Learning about minerals is fun, I enjoy swapping minerals, most of my collection is either selfcollected or swapped.

My main interests and focus are in systematic mineralogy, minerals from alkaline deposits and granitic pegmatites. I have written several articles, mostly on Norwegian minerals, and is one of the co-authors of the book "The Langesundsfjord. History, geology, pegmatites, minerals". Bode Verlag Gmbh 2010. In 2001-2009 I was the chairman of the NAGS (Norges Amatørgeologiske Sammenslutning), an umbrella organization for Norwegian collectors and rockhounds. Currently I am co-editor of the Norwegian magazine, STEIN ( Since 2001 I have also enjoyed being one of the organizers of the yearly Mineralsymposium in Norway.

Having been a member of Mindat's Management team since 2009, I have tried to do my best - in my spare time- to do what I can to improve this fantastic database by adding, checking, correcting etc. especially on the locality pages and mineral pages. My focus has naturally been on the Scandinavian countries and Madagascar, which are those countries I knew best. I speak beside norwegian, also malagasy, english and some french. In addition I read and understand well french, danish, swedish and german.

Feel free to contact me. However, since I also have a job and family, and also travels much in my job, the answer may be delayed, which I apologize for in advance.

Some of the photos posted here are from the collection of a friend of mine, Roy Kristiansen (kristiansenite) a dedicated norwegian amateur mineralogist and mycologist. If you want to learn more about Roy, go to his homepage
