The Buehler PetroThin is a thin section machine designed for sectioning a variety of samples. Our precision thin section machines come with a diamond cutting

As part of our studies on warm asphalt mixture production at about 100 °C using foamed bitumen Åldringsgraden hos de gamla bindemedlen; flera bindemedel åldrades i en Thin Film Oven. • Bitumenkälla och Anorthosite, NO. Sparagmitt in Dünnschliffen [On the behavior of canada balsam in thin sections].
This has come from an area dominated geologically by a large pre-cambrian anorthosite intrusion. Rounded-granular plagioclase and quartz with areas of intergrowth, with pink embayed garnet. Thin section slides are precisely ground to a thickness of 0.03 mm across the entire specimen area. Mineral and rock thin sections are mounted on 27 x 46 mm microscope slides, and protected by a glass coverslip.
Grenville Province anorthosite massifs were derived from depleted mantle. It is not clear whether massifs and related mafic intrusions throughout the Nain Province of Labrador were derived from enriched mantle, or were contaminated by early Archean (greater than 3500 Ma) silicic crustal materials, heretofore thought to be restricted to coastal Labrador.
So, take a look at the thin section pictures for the three lunar basalts below, and give these three rocks textural names! Lunar Basalt 12002, Apollo 12. Lunar Basalt 12005, Apollo 12. Lunar Basalt 70017, Apollo 17. Question 2: Intersertal and Intergranular textures occur on the Earth in Mid Ocean Ridge Basalts, which are erupted on the bottom of the sea
The method uses the Michel The locality contained ultramafics. Greenish olivine and black hornblende are absent, and the hardness of 5.5 also ruled out these minerals as well as the feldspars.
The former rocks of this study are located in the southern part of TIB, in the late Olle Wallner, who without complaints prepared an endless row of thin sections. model for the origin of the gabbro-anorthosite-syenite-potassic granite suite.
BRECCIA chert in silica dolomite matrix . 11 This is a thin section of Gabbro from the tertiary volcanic centre in Ardnamurchan, on the West Coast of Scotland. Famous for its complete ring dyke made of Eucrite, a similar gabbro. This sample was collected from a Part of the Hypersthene gabbro at Sanna Point.
The stone tables are made of marble, gabbro and anorthosite. A polished thin section of c millimetres is sampled from a rock and examined with a polarising

Damage produced during thin section grinding causes speckles of light in the biotite, where the crystal lattice has been deformed. Zoisite developed in pagioclase in an anorthosite.

Famous for its complete ring dyke made of Eucrite, a similar gabbro. This sample was collected from a Part of the Hypersthene gabbro at Sanna Point. CaO values can be influenced by scapolite alteration or contamination by thin calcite veins (Morrison and Valley, 1991). The leucogabbros display large variations in trace-element concentrations, ranging from low concentrations similar to anorthosite in less mafic varieties to higher concentrations similar to gabbros in more mafic varieties. 11 clasts and studied thin sections of them.

(1985) studied basalts from the processing fines. But Paul Warren made the most fuss, so we shall start with his observations: c1 (W-101) from ,46 and ,116 Massif anorthosite • Layring is not found in massif anorthosite. • It contain plagioclase of An35-65 range. 14. ORIGIN of anorthosite Magmatic Origin: Massif anorthosite are magmatic and layered anorthosites are magmatic differentiation. • It has been derived from a basic magma either grabbroic or … Anorthosite is a rock type of the mafic-ultramafic succession, The thin section above doesn't allow evaluation of textures that may be related to overgrowths.

Modal analyses of thin-sections have been carried out on 51 rock samples from outcrops and on 5 rock samples from the drillcore in borehole KLX0 .
