We describe a laser fluorination technique specifically for quartz that allows both high-accuracy and high-precision determination of oxygen isotope ratios, regardless of grain size. The rapid heating, defocused beam technique (RHD) utilizes a defocu

The convergent margin of Peru, characterized by an extensional tectonic regime and the lack of a well-developed accretionary prism, has been investigated by a deep-sea submersible during the Nautiperc cruise (March–April, 1991). This allowed the co

The isotopic compositions of oxygen, hydrogen, carbon and sulfur have been determined on silicate, carbonate and sulfide samples from auriferous tourmalinized sandstone, its footwall and hanging wall, of Birimian age (2.1 Ga), at Loulo, in Mali. The

Isotopic analyses of the S in sulphides and sulphates from formation waters were made at 35 geothermal wells exploiting the Dogger geothermal aquifer of the Paris Basin. Isotopic analyses of the O of the dissolved sulphates were also made on 12 of th

The minerals of basic and acidic rocks from the volcano-sedimentary sequence in the Huelva area, Spain, Iberian Pyrite Belt, display an extendedδ18O enrichment. Quartzδ18O values from quartz-keratophyres vary from +10.5 to +17.0 and feldsparδ18O v

Two deep geothermal boreholes were drilled in the Asal Rift in the Republic of Djibouti. The first hole, Asal 1, produced water and steam, temperatures of up to 250°C being recorded at the well head. The second hole, Asal 2, produced minute amounts
