1. Dating stalagmite from Caverna do Diabo (Devil´S Cave) by TL and EPR techniques
ABSTRACT A cylindrical fragment of stalagmite from Caverna do Diabo, State of São Paulo, Brazil, has been studied and dated by thermoluminescence and electron paramagnetic resonance techniques. The thermoluminescence glow curves of stalagmite samples and subsequently gamma irradiated, have shown rise of three peaks at 135, 180 and 265 °C. From electron par

2. Modelagem e renderizaÃÃo da gÃnese e crescimento de espeleotemas em tempo-real / Modelagem e renderizaÃÃo da gÃnese e crescimento de espeleotemas em tempo-real
Among the many natural phenomena already studied in computer graphics research, the interior of caves remains largely unexplored. We present in this paper a plausible approach, based on Geological studies, for modeling the genesis and growth of speleothems. Speleothems are mineral depositions formed in caves, such as stalactites, stalagmites and columns. Our

3. Metodologia de datação em carbonatos pela série de desequilíbrio do urânio por espectrometria de massa
There are many dating methods largely used according to the kind of material to be dated. Methods that rely on the time-dependency of geochemical disequilibrium 238 235 232 U, U and Th natural decay system, between daughter and parent isotope, from the whose final members are stable Pb isotopes, are the most useful in a broader variety of geological, hydrolo
