Morphology and distribution of lakes under the Laurentide Ice Sheet: implications for ice flow dynamics

Boreas, EarlyView.
This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.

Meteorite cloudy zone formation as a quantitative indicator of paleomagnetic field intensities and cooling rates on planetesimals

, 2019
Metallic microstructures in slowly-cooled iron-rich meteorites reflect the thermal and magnetic histories of their parent planetesimals. Of particular interest is the cloudy zone, a nanoscale intergrowth of Ni-rich islands within a Ni-poor matrix that ...

The Development of a Coherent Museum Collection Database Management System‐Some Reflections on the Process

Curator: The Museum Journal, EarlyView.
ABSTRACT The article describes and reflects the development of a coherent interdisciplinary collection database management system of a large natural history museum. The internal and external requirements were analyzed and informed the technical development of the database. In parallel, staff skills increased and work routines were optimized.

Classification of stony meteorites and chondrules – the case of meteorite Jesenice

Geologija, 2012
In the first part of the paper there is a description about genesis of meteorites, in particularly about stony meteorites– chondrites, since meteorite Jesenice is an ordinary L chondrite. Chondrules represent main part of the mass ofchondritic meteorites.

A Portable Magnetometer for Magnetic Measurements of Meter‐Sized Meteorites

Geochemistry, Geophysics, Geosystems, 2020
Meteorites contain records of past magnetic fields in the form of natural remanent magnetization (NRM). A key property of meteorite magnetization that provides information about its origin is its dependence on spatial scale.

The nature and formation of silica minerals in eucrite meteorites: Insight into the protoplanetary magma crystallization

Meteoritics &Planetary Science, EarlyView.
Abstract Silica polymorphs in meteorites provide critical constraints on crystallization processes associated with thermal activity in the early solar system. A detailed investigation of silica polymorphs in eucrites (the largest group of achondrites) using cathodoluminescence imaging and laser‐Raman spectroscopy revealed significant variations in the ...
