The 4 km deep pilot research drill hole of the German Continental Drilling Project has been used to sample fluids from the fracture pore space of granites and gneisses of the continental crust. The open hole and water entry points are located in the section from 3.85-4.0 km. The rocks are...

These values are indistinguishable from that of the mantle (ɛ205Tl = −2.0 ± 0.557,58,59) and continental crust (ɛ205Tl ~ −260), and likely reflect the dominance of terrigenous input in both locations. Minor amounts of manganese oxide may be responsible for heavier Tl ...

Here we show He-3/He-4 ratios in geothermal springs along a 500-km segment of the KKF are 3-100 times the normal ratio in continental crust, providing unequivocal evidence that a component of these hydrologic systems is derived from tectonically active mantle. Mantle enrichment is absent alon...
rapidly in the direction of easiest pressure relief. Upward propagation of fluid-filled fractures, so-called mobile hydrofractures (Dahm2000; Bons2001), enables the transport of large fluid volumes to the upper crust. Precipitated mineral phases and fluid inclusions may conserve the thermodynamic and...
The inferred stress regime, including due to uplift of the Deccan Plateau, triggered by erosion of basalt cover is likely to be confined mostly in the upper part of the crust. Existence of a low velocity, high conductivity fluid filled layer will enhance stress concentration in the uppermost ...
