A living record of tremolite, tectonics, and what the rock is actually telling us.
Tremoloid publishes long-form field notes, lab observations, and mineralogical essays from working geologists, mineralogists, and backcountry survey crews. Slow reading. Honest data. No press releases.

Cleavage planes, cold hands: three days at the Calumet tremolite outcrop.
A first-of-the-season visit to a long-quiet lens in the Grenville metasediments. We came back with twenty-two samples, a revised strike measurement, and a small argument about whether the host calcite is recrystallized or just tired.

What the crew filed this month.
Six recent notes from the journal — long enough to earn their place, short enough to finish in a sitting. We post one to two a week, never on a schedule we can't keep.
Where tremolite ends and actinolite begins: a working line for the field lens.
A practical rule of thumb for the 10× loupe, with three counter-examples from this season's traverses.
Notes from the brittle-ductile transition, with a tape measure and a thermos.
Why the classic cartoon of a single sharp boundary keeps failing us in the metasediments of the southern shelf.
Reading tremolite's second-order birefringence without losing your place at the scope.
A small set of habits that have saved me a lot of slide time over the years, with a checklist at the end.
What the 1893 Tremolite Mining Company annual report actually says — and what it skips.
Reading an old report against the modern mine plan is a humbling exercise. Here are the four passages that matter most.
Cleavage planes, cold hands: three days at the Calumet tremolite outcrop.
First-of-the-season visit to a long-quiet lens in the Grenville metasediments, with samples and a small argument.
