Sedimentation in Volcanic Settings
We have gained considerable experience with volcaniclastic materials over the past 30 years, but the field has undergone considerable growth in the decade following the 1980 eruption of Mount St. Helens. This eruption resulted in an accelerated research in explosive volcanic products and spurred a renewed interest in volcaniclastic materials as they relate to plate tectonic boundaries and explosive volcanism in general. Since the early 1970s a loosely defined field called â∈œsedimentary tectonicsâ∈ has emerged. A large part of the field of sedimentation and tectonics includes studies of volcaniclastic sedimentation, largely because of the direct association of tectonism, volcanism and sedimentation. This book attempts to illuminate the field and to present its salient features to sedimentologists not generally versed in volcaniclastic particles, deposits or facies.
Volcaniclastic Deposits: Implications for Hydrocarbon Exploration
Published:January 01, 1991
Recent developments in sedimentology, diagenesis, and hydrocarbon exploration suggest that the recognition and interpretation of volcaniclastic sediments can significantly influence exploration methods, and the prediction of reservoir geometry and quality in volcaniclastic sequences.
Volcaniclastic sediments are characterized by predictable changes in composition, texture, geometry and distribution, which can be used during both geologic and seismic interpretation. Interpretations based on volcaniclastic sediments help to better define the volcano-tectonic and paleogeographic setting that controls the deposition of associated siliciclastic and/or carbonate reservoirs. Volcaniclastics are also important to an understanding of the thermal history of a sedimentary basin and its deposits, and...
