How to make rock thin sections, without much equipment

as it becomes so thin. A few swipes on the lap can turn an almost-done into half-ruined. A hard, quartz-rich rock like granite or gneiss will take longer than a softer sedimentary or metamorphic rock. I mostly make thin sections of basalt, which is the dark gray type of lava. It is fine-grained

How to make a thin section - DaveHirsch

A thin section is a 30 µm (= 0.03 mm) thick slice of rock attached to a glass slide with epoxy. Typical thin section slides are 26 mm x 46 mm, although larger ones can be produced. They are generally covered by another glass slide, a cover slip also attached to the rock with epoxy.

Preparing a Thin Section of a Rock

A thin section of rock is prepared so mineralogists and petrologists can identify, study, and analyze the material more closely. This is known as thin section preparation. Using this method, you can classify minerals, identify problems in quarries or structures, examine mineral potential in geological environments, and identify the geographical source of archaeological artifacts.

I then embarked on a thin section exploration of many fossils and fossiliferous rocks. I have made sections of bones from the Devonian through the Pliocene and teeth as well. This technique lends itself well to making good use of bone chips and fragments, particularly if the parent creature is known.

DIY Thin Sections! – JOIDES Resolution

Seeing Through Rock. The crew aboard Expedition 376 are the first to shine a light on cores retrieved from an active submarine volcano. But if we really want to know what’s inside these rocks, we need to shine a light through them. To achieve this, we prepare thin sections.. A thin-section is a slice of rock 30 microns thick.

Rock thin section: andesite - USGS

Detailed Description. Photomicrograph of sample 09RDWES301 - an andesite collected during the Redoubt 2009 eruption. A rock thin section is created by gluing a small piece of rock onto a glass slide, then grinding it down to a thickness of 30 microns (the average human hair is about 100 microns in diameter) so that light shines through it when examined under the microscope.

Ultra-thin sections. Fine-grained rocks, particularly those containing minerals of high birefringence, such as calcite, are sometimes prepared as ultra-thin sections.An ordinary 30 μm thin section is prepared as described above but the slice of rock is attached to the glass slide using a soluble cement such as Canada balsam (soluble in ethanol) to allow both sides to be worked on.
