siltstone ngsi

Jalal-Abad iron deposit is located about 38 km northwest of Zarand town in Kerman Province. It contains 200 Mt iron ore with average chemical composition of Fe = 45%, S =1.18% and P = 0.08%. Iron mineralization occurs in an Early Cambrian volcano–sedimentary sequence of Rizu series which is composed of sandy siltstone, siltstone, volcanoclastic rocks and dolomite. Small intrusive bodies of gab...

Matuyama–Brunhes geomagnetic reversal record and associated key tephra layers in Boso Peninsula: extraction of primary magnetization of geomagnetic fields from mixed magnetic minerals of depositional, diagenesis, and weathering processes

Journal: :Earth, Planets and Space 2022

Abstract We report paleomagnetic records of Matuyama–Brunhes geomagnetic polarity reversal and associated key tephra layers from the Early–Middle Pleistocene marine sedimentary succession in Boso Peninsula. The outcrop is Terasaki, Chiba, Japan ~ 25 km northeast Chiba section. sediment consists a massive siltstone layer Kokumoto Formation, Kazusa Group. A was identified middle with chemical com...

The middle Pleistocene Merced-2 and -3 sequences from Ocean Beach, San Francisco

2002

R. M. Carter

The Merced Formation comprises a 2-km-thick shallow marine and non-marine succession that was deposited in a small transtensional basin along the San Andreas Fault during the late Pliocene to middle Pleistocene. The sediments dip between 10j and 80j to the northeast, and are locally disrupted by small faults. During tilting, the beds have been rotated into subparallelism with the San Andreas Fa...
