...James N. Murdock abstract A seismic-refraction experiment was conducted in the Melones Reservoir region of the metamorphic belt of central California in May 1972. The experiment was designed to produce data for analyses by seismic-refraction-line and time-term methods. The belt is geologically...

... where water recharge is still occurring, such as the regions close to the El Melon–El Viento high (following the hydraulic-head maps), it is very likely that biodegradation is still active and thus cold meteoric water is reaching the reservoirs ( Figure 3 ). Therefore, we prefer the idea...

...) and the surrounding sulphide powders (diffusion source). Diffusion coefficients of (Cu+In) in ZnS were experimentally determined. The nature of the DIS phases (intermediate solid solution, cha1copyrite, bomite, digenite) and the corresponding textures (dusty, blebs, worm-like, water-melon) depend on the Fe content...

... that reflect changes in basement composition and the degree of organization of magma sources. We use these data to appraise different reservoirs contributing to the magma sources and have applied mass balance, mixing, and assimilation–factional crystallization (AFC) models to evaluate budgets...

... deterioration in very low dipping beds. Many traps in the Orinoco HOB, such as the Guanoco field and the shallow Quiriquire field, are recognized as tar traps ( Salvador and Leon, 1992 ). The Melones field in the Orinoco HOB contained 1.5 billion bbl of 8.2° to 10.3° API oil in a shallow reservoir dipping 1...

This is also reflected in 187 Re/ 188 Os ratios of samples, ranging from 0.218 to 0.293, that are significantly lower than...

Notable also is the coincidence between the inferred temperature ranges for the basal seismogenic zone with estimated temperatures of overpressured hydrothermal solutions responsible for Au‐quartz mineralization, which hints at the presence of a substantial fluid reservoir...

Production in the Heterostegina zone had been found previously but the Frio production in this pool should be attributed to 1939. TABLE I...

... argue against extensive differentiation in the upper crust (e.g., Keller et al., 2015 ). Still, large-volume eruptions equilibrated at upper-crustal pressures attest to the presence of large upper-crustal magma reservoirs (e.g., Bachmann and Huber, 2016 ). Solidified shallow-crustal plutons...

The lower 1 m of the soil column acts as a reservoir and drains the water out from the soil column at the bottom, due to the gravity forces ( Chen and Dudhia, 2001 ).

Dissolution and reprecipitation of these minerals by migrating brines could be important factors in geochemical segregation processes...
