IN THE MISTASTIN LAKE AREA GENERAL INFORMATION The geology of the Mistastin batholith in Geology : Mistastin Lake book and around the Québec border (Figures 1 and 2A) is very poor-ly known. Mistastin Lake itself fills a Cenozoic meteorite crater, around which remnants of a impact melt sheet occur, and this is the only area that has received detailed study.
This thesis investigated the nature of parautochthonous and allochthonous impactites found in the erosional remnant of the central uplift of the Mistastin Lake impact structure, central Labrador.
This was carried out with the goal of discovering details about the composition and formation conditions of these complex materials. This study involved fieldwork and a range of laboratory techniques.
Results from a day analogue deployment at the Mistastin Lake impact structure in Labrador, Canada suggest that scale, relief, geological detail, and time are intertwined issues that impact the mission control science team’s effectiveness in interpreting the geology of an area.

The Mistastin Lake impact structure is defined by a ~28 km diameter circular, ring of hills surrounding Mistastin Lake that contains two islands in its centre .
Based on the DEM generated for this study, the maximum height of this ring ranges from to m above lake level, and. The Mistastin Lake impact structure, known locally as Kamestastin, located in central Labrador, Canada (55°53′N; 63°18′W), is comprised of an oval‐shaped lake located in a large depression that is enclosed by an approximately 28 km diameter ring of hills—generally regarded as being the remnant crater rim (Grieve ).
There is an.

He was one of two guides leading an expedition to the remote lake for clients from the United were no. The presence of two titanomagnetite phases in the Mistastin Lake trachy-andesitic melt rocks is typical of basaltic lava flows (Ade-Hall et al.,Grommé et al.,Petersen, ) and is one reason why Currie and Larochelle () interpreted the impact melt rocks as volcanic in origin.
Raman microprobe (RMP) spectra were made of naturally shocked (27–32 GPa) microcline from Lake Mistastin which showed the optical characteristics common to shocked minerals, i.e. loss of birefringence, strongly deformed twin planes in still birefringent material, etc.

Marion, C., *Sylvester, P. and Leitch, A. Variable thickness of the impact melt sheet at Mistastin Lake Crater, Northern Labrador, GSA. The Mistastin Lake crater was chosen because it is expected to have the same structure and geology as the future mission target: the Moon’s South Pole Aitken (SPA) basin.
Mistastin Lake is one of the only identified Earth based impact structures to have a similar rock composition to the Moon’s south pole. Mistastin Lake crater was created when a five-kilometre-wide asteroid exploded near the surface of the Earth just east of what is now the Labrador-Quebec interprovincial boundary 38 million years.
Mistastin Lake Impact Structure. The Mistastin Lake impact structure is located in central Labrador, Canada (55°53′ N; 63°18′ W). It is a complex crater structure of approximately 28 km diameter (Grieve ).

Beauchamp assisted with collection of data using a JEOL JXAF Field Emission Electron Probe Microanalyzer (FE-EPMA). Chapter 7 provides a summary of the suitability of the Mistastin Lake impact structure as a lunar analogue site.

Here, we focus on the results and lessons learned from a robotic precursor mission and follow on human-robotic mission to the Mistastin Lake impact structure in Labrador, northern Canada (55°53'N; 63°18'W).
The Mistastin structure was chosen because it represents an exceptional analogue for lunar craters. The ±12 m.y., 25 km diameter Boltysh impact crater was formed in Precambrian granites and granite gneisses of the Ukrainian Shield.
The crater deposits have undergone minimal post-impact erosion and it is possible to study a complete vertical section of the underlying ∼ m thick melt sheet. The melt rocks, as sampled in two drill holes, can be subdivided into two major textural classes.
Today, Mistastin Lake still looks like a crater from space, even though it’s filled in with water. After the asteroid hit, the site was home to a massive crater that stretched for 17 miles (28 km). Table' offormations - Lake Sr. Martin area. 9 2. Chemical analyses of select:d samples, St.

According to a new paper in Earth and Planetary Science Letters, geologists have found evidence of zircon being transformed into cubic zirconia around Mistastin crater.
