Torres Alvarado Muharrem Satir Ciencias de la Tierra element mobility Geothermal systems Mexican Volcanic Belt hydrothermal alteration Qualitative and semi-quantitative studies of element mobility at Los Azufres geothermal field, Michoacán, Mexico, werecarried out, in order to get a better understanding of the hydrothermal alteration processes that affected the volcanic rocks fromthis area. X-ray fluorescence techniques were applied to analyse well cuttings and drill cores from wells Az-3, Az-26 and Az-52 atdifferent depths. With these analyses a 2000-m thick volcanic sequence was recorded. Geochemically these rocks form a calcalkalinetrend from basaltic to rhyolitic composition. Comparing the chemical composition of altered samples with that of freshsamples from the surface we find relatively low element mobility during alteration. Simple calculations of element loss and gainindicate a weak silicification and low mobility of alkalis. 1998 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56837305 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.37 |
