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

open access: yesNear 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

Bayesian classification for dating archaeological sites via projectile points [PDF]

open access: yesarXiv, 2020
Dating is a key element for archaeologists. We propose a Bayesian approach to provide chronology to sites that have neither radiocarbon dating nor clear stratigraphy and whose only information comes from lithic arrowheads. This classifier is based on the Dirichlet-multinomial inferential process and posterior predictive distributions.

Stratigraphy of the Hawai'i Scientific Drilling Project core (HSDP2): Anatomy of a Hawaiian shield volcano [PDF]

open access: yes, 2007
The Hawai'i Scientific Drilling Project (HSDP2) successfully drilled ∼3.1 km into the island of Hawai'i. Drilling started on Mauna Loa volcano, drilling 247 m of subaerial lavas before encountering 832 m of subaerial Mauna Kea lavas, followed by 2019 m ...

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

open access: yesArchaeological 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

open access: yesNear 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

Taxonomy and stratigraphy of an algal assemblage in Palaeogene deposits of the northern foothills of Mt. Biokovo (Southern Croatia)

open access: yesGeologia Croatica, 2012
A rich algal assemblage at the Kozica locality, in the northern foothills of Mt. Biokovo, contains, among other forms, Praturlonella salernitana BARATTOLO. In addition, the descriptions of Clypeina bucuri BARATTOLO & ROMANO and C.

Dating glacier ice of the last millennium by quantum technology [PDF]

open access: yes, 2018
Radiometric dating with 39Ar covers a unique timespan and offers key advances in interpreting environmental archives of the last millennium. Although this tracer has been acknowledged for decades, studies so far have been limited by the low abundance and radioactivity, thus requiring huge sample sizes.

Evolution of major sedimentary mounds on Mars [PDF]

open access: yesJournal of Geophysical Research - Planets, 121, 2282, 2017
We present a new database of $>$300 layer-orientations from sedimentary mounds on Mars. These layer orientations, together with draped landslides, and draping of rocks over differentially-eroded paleo-domes, indicate that for the stratigraphically-uppermost $\sim$1 km, the mounds formed by the accretion of draping strata in a mound-shape.

Dynamic Stratigraphy: An Introduction to Sedimentation and Stratigraphy

open access: yesEos, Transactions American Geophysical Union, 1985
This text is an expanded and updated edition of the original 1974 volume. The prose is aimed at an undergraduate readership and is clear and concise. The subtitle of the book, however, gives a better idea of its contents than does the main title, as a significant proportion of the text is devoted to the development and description of sedimentation ...

Drone‐Based High‐Resolution LiDAR for Undercanopy Archaeology in Mediterranean Environment: Rusellae Case Study (Italy)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper presents a novel methodology and workflow successful in identifying and mapping undercanopy archaeology in woodland Mediterranean areas. The study area is characterized by dense vegetation typical of the Mediterranean area, located in southern Tuscany (Italy), within the territory of the ancient city of Rusellae next to the ...
