摘要：
REE in fluorite from Asturias show different content and distribution patterns from east (Berbes) to west (Villabona). The linear trend of the data in a Tb/Ca vs. Tb/La diagram hints at crystallization from a single hydrothermal event, Berbes being the early stage and Villabona occurring later. (87)Sr/(86)Sr ratios of fluorite are distinct in each area and vary from 0.70802 to 0.71052. This is consistent with the presence of two Sr sources: seawater of Lower Jurassic age and a more radiogenic source of basinal origin that interacted with basement rocks. REE patterns and Tb/Ca ratios are compatible with the presence of a unique hydrothermal system that probably flowed from east to west leaching different rocks during early Jurassic times.
