Chemical laboratory

Additional facilities are a chemical lab for preparation and synthesis of rock magnetic samples. There is also a rock preparation room in 'Remise C' of the Fort. 

Field equipment comprises Stihl/Husqvarna/Echo engine drills, Makita electrical drills with Honda generator, Makita 18V battery poered drills

Further, there is access to the faculty's equipment, like TEM, SEM, LAM-ICP-MS MicroProbe, XRF, isotope analysis, and more.
