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.

A micro‐geoarchaeological investigation of a cultivation pit (maite) on Teti'aroa atoll, Central‐East Polynesia

Archaeology in Oceania, EarlyView.
ABSTRACT Cultivation pits represented the principal form of horticultural features developed by past atoll communities in Central‐East Polynesia (CEP), and they are still utilised on some atolls in Oceania. The majority of information about the use of cultivation pits in CEP derives from ethnographic and preliminary archaeological investigations.

Petrophysical target characterization with lithogeochemical clustering: the Metsämonttu Zn–Pb–Cu deposit, southern Finland

Near Surface Geophysics, Volume 20, Issue 6, Page 637-660, December 2022., 2022
ABSTRACT In mineral exploration, reliable and comprehensive petrophysical groundwork helps evaluate the success rate of applying geophysical methods to the target and thus improves the quality of decision‐making related to geophysical surveys. Petrophysical data for potential field exploration can be efficiently collected from drill cores together with

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.

Cost‐effective in‐mine seismic experiments to image platinum deposits and associated geological structures at Maseve platinum mine, South Africa

Near Surface Geophysics, Volume 20, Issue 6, Page 572-589, December 2022., 2022
ABSTRACT The detection of mineral deposits and their related geological structures is of great importance to the mining industry as structures (such as dykes and faults) can affect the safety, cost and efficiency of mining. With the goal of testing cost‐effective seismic methods for mineral exploration and mining, active and passive seismic experiments
