Louth Crater: Evolution of a layered water ice mound [PDF]

Icarus (2008) 196, 433-445, 2014
We report on observations made of the ~36km diameter crater, Louth, in the north polar region of Mars (at 70{\deg}N, 103.2{\deg}E). High-resolution imagery from the instruments on the Mars Reconnaissance Orbiter (MRO) spacecraft has been used to map a 15km diameter water ice deposit in the center of the crater.

Waste Management and Waste Disposal Detected by Combination of Analytical Methods: Late Bronze Age Březnice Settlement Site (South Bohemia)

Archaeological Prospection, EarlyView.
ABSTRACT Waste disposal processes and landfill management are crucial subjects in the field of settlement archaeology. Our study is focused on understanding the processes that are connected to the formation of the infills of settlement features and the recycling of the building materials (daub and wood) and waste management.

Sedimentary Characteristics and Lithological Trap Identification of Distant Braided Delta Deposits: A Case on Upper Cretaceous Yogou Formation of Termit Basin, Niger

E3S Web of Conferences, 2018
Lithological trap identification in thin sand and thick shale layers is still a challenge for hydrocarbon exploration. Based on the high-resolution sequence stratigraphy theory and the establishment of high-resolution sequence stratigraphy framework with

Multidisciplinary Approach to Identifying Early Mediaeval Gates: A Case Study of the Břeclav–Pohansko Stronghold

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a comprehensive approach to verifying a presumed western gate at Pohansko by integrating nondestructive geophysical methods (ERT, magnetometry and core prospection) with traditional archaeological excavation. The identification and characterization of gates by nondestructive methods within early mediaeval fortified sites ...

Sequence Stratigraphy of Middle Albian to Cenomanian sediments (Sarvak Formation) in Tang-e-Chenarbashi (southeast Ilam) and role of fossil fauna for recognition and interpretation of the depositional sequences [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2018
Middle Albian to Cenomanian strata of the Sarvak Formation indicate pelagic facies in Tang-e-Chenarbashi stratigraphic section. These strata deposited in five sequences of the third order and nine sequences of the fourth order.

Late Miocene to early Pliocene biofacies of Wanganui and Taranaki Basins, New Zealand: Applications to paleoenvironmental and sequence stratigraphic analysis [PDF]

, 2004
The Matemateaonga Formation is late Miocene to early Pliocene (upper Tongaporutuan to lower Opoitian New Zealand Stages) in age. The formation comprises chiefly shellbeds, siliciclastic sandstone, and siltstone units and to a lesser extent non-marine and

Is there a role for sequence stratigraphy in chronostratigraphy?

Stratigraphy, 2007
Sequence stratigraphy revolutionized the field of stratigraphy in the late 1970s and 1980s by providing an interpretive depositional framework for integrating diverse stratigraphic data at the scale of sedimentary basins. However, a lack of consensus on criteria for recognizing, mapping and hence dating sequence boundaries, interpretations of uneven ...

Mapping Ancient Structures and Demonstrating Integrated Archaeological Geophysics at Huacas de Moche, Peru

Archaeological Prospection, EarlyView.
ABSTRACT At the Huacas de Moche (HdM), one of the most prominent archaeological sites in Trujillo, Peru, the needs of an expanding modern community are in direct conflict with the desire to preserve the wealth of archaeological information. The undetermined extent of the HdM site introduces disputes in land usage where potential archaeological features
