Mineralogy
Atomic lattices, cleavage planes, and the optical signatures that let us read a hand specimen under the petrographic microscope. Tremolite, actinolite, and the amphibole supergroup lead the catalogue.
The Tremoloid Index
Topics in Earth Science
A curated map of the disciplines we cover — from the crystallography of tremolite to the slow choreography of plate tectonics. Each topic gathers field reports, peer notes, and editorial deep-dives written from the outcrop, the lab bench, and the seismic stack.
Disciplines covered across the site
Eleven working topics, each a live index of field notes, literature reviews, mineralogical monographs, and expedition dispatches. Counts update with every published piece.
Tectonics & Structural Geology
Plate boundaries, fault-zone fabrics, and the kinematic reconstructions that turn strike measurements into a story about mountain belts and rifted margins.
Petrology
Igneous, metamorphic, and sedimentary rock systems — phase equilibria, geothermobarometry, and the textures that reveal whether a greenstone was once a seafloor or a subduction channel.
Seismology
Wave propagation, focal mechanisms, and the seismic tomography that lets us image slabs descending into the mantle in near real time.
Geochemistry
Isotope systems, trace-element partitioning, and the chemical fingerprints that link a serpentinite to its mantle source or a zircon to its parent magma.
Hydrogeology
Aquifer dynamics, karst conduits, and the slow flow of groundwater through fractured crystalline basement — including the tremolite-bearing marble aquifers of the Alps.
Volcanology
Eruption dynamics, magma storage, and the petrogenetic clocks that bracket an arc volcano's history between repose and paroxysm.
Stratigraphy & Sedimentology
Layer-cake reading at the outcrop scale: bedforms, unconformities, and the depositional architectures that encode sea-level, climate, and basin subsidence.
Geomorphology
Landscape evolution, erosion rates, and the interplay between tectonic uplift and surface processes that sculpt ridges, valleys, and pediment surfaces.
Paleontology
Body and trace fossils as biostratigraphic and paleoenvironmental indices, from the Ediacaran to the Quaternary, with regular contributions on Lagerstätten preservation.
Planetary Geology
Comparative planetology from a field geologist's vantage: wrinkle ridges on Mercury, the canyon systems of Valles Marineris, and the icy shells of Europa.

Three ways to navigate the topics
Each topic page collects related reading, field photography, and contributor profiles. Pick an entry point that matches the depth you want.
By Discipline
Start with a broad subject — mineralogy, tectonics, seismology — and follow the editorial thread downward into narrower sub-topics and case studies.
By Region
Open a topic and filter by field site — the Western Alps, the East African Rift, the Andes, the Basin and Range — to read the geology through its geography.
By Contributor
Each author page lists the topics they write about, their field affiliations, and ongoing research threads — useful when you want a single voice to follow.
Pitch a topic you know deeply
Tremoloid publishes long-form, field-verified writing. If you have a working knowledge of any subject listed here — or a neighboring one we should add — the submissions desk is open.
