A new technology of classifying a seismic interval parallel to a horizon in a 3D volume based on the shape of the wiggle traces and its geologic use will be presented here. Since the seismic traces contain all relevant information, such as, reflection patterns, phase, frequency, amplitude etc., the trace shape is a fundamental property of the seismic data. A map showing the distribution of simi...

The potential use of a nonlinear deterministic framework for understanding the dynamic nature of solute transport processes in subsurface formations is investigated. Time series of solute particle transport in a heterogeneous aquifer medium, simulated using an integrated probability/Markov chain (TP/MC) model, groundwater flow model, and particle transport model, are studied. The correlation di...

Petrographic and geochemical analyses of travertine-depositing hot springs at Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, have been used to define five depositional facies along the spring drainage system. Spring waters are expelled in the vent facies at 71 to 73 degrees C and precipitate mounded travertine composed of aragonite needle botryoids. The apron and channel facies ...

Abstract The Jebel Oust region (north-eastern Tunisia) recorded two levels of marine black shale in the Lower Cretaceous marly series. Geodynamic evolution, biostratigraphic and Rock–Eval analysies allow classifying those shales as unconventional oil resource systems that were deposited during oceanic anoxic events: Middel Barremian Event "MBE" Early Aptian "OAE1a". Paleogeographic evolution hi...

This paper is a synthesis of the use of selected trace elements as proxies for reconstruction of paleoproductivity and paleoredox conditions. Many of the trace elements considered here show variations in oxidation state and solubility as a function of the redox status of the depositional environment. Redox-sensitive trace metals tend to be more soluble under oxidizing conditions and less solubl...

Carbonate-rich sandstones (samples 0708 and 0704) were collected from outcrop of the Gunflint Formation, Ontario, Canada (sample 0708: 48°29 ′24.4′′ N, 89°11′34.2′′ W; sample 0704: 48°29′24.6′′ N, 89°11′35.3′′ W). Samples contain 0.34 and 0.23wt% organic carbon. The estimated age for the Gunflint Formation is ca. 1.9 Ga (Fralick et al., 2002), and its metamorphic grade is considered to be sub-g...
