Macrostrat

• Get the geology at a pointFind out what rock is at a place: the map unit of the most detailed geologic map there, with its name, age in millions of years and named intervals, rock types, description, the Macrostrat rock units matched to it, any fault mapped there, the ground's elevation and the map's citation.
• List map units at a pointList every geologic map unit at a place, from the most detailed local map to the global one, each with its age, rock types, description, matched Macrostrat units and its map's citation.
• Find geologic mapsFind the geologic maps Macrostrat holds for a place, or every map it holds, with each map's title, authors, year, publisher, DOI, scale and citation.
• Search geologic map unitsFind the units of geologic maps anywhere in the world by words in their descriptions, such as banded iron, or list one map's legend, with each unit's age, rock types, description and map citation, the largest first.
• Find stratigraphic columnsFind Macrostrat's stratigraphic columns (the rocks under a region, top to bottom) at a place, or holding rocks of a stratigraphic name, age, rock type, environment or economic use, each with its age range, rock types, unit count and sources.
• Get a columnGet one stratigraphic column by its ID: where it is, its age range, rock types, environments and sources, and every rock unit in it from the top down. 'Found' is false when Macrostrat has no such column.
• Search rock unitsFind rock units (formations, members and beds in Macrostrat's columns) by stratigraphic name, age, rock type, environment, economic use, place or column, each with its age and named intervals, thickness, rock types and their shares, environments and the references it is compiled from.
• Get a rock unitGet one rock unit by its ID: its names, column, age and named intervals, thickness, rock types and their shares, environments, economic uses, the units above and below it, where it was when it formed, and its references. 'Found' is false when Macrostrat has no such unit.
• List fossil collectionsList the Paleobiology Database fossil collections matched to a rock unit, a column, a stratigraphic name, a time interval or an age, each with its age, how many fossils it holds and a link to it.
• List measurementsList the measurements made on samples of a rock unit or column, or every measurement of one kind: element concentrations, isotopes, radiometric ages and paleocurrent directions, each with its values, sample and source.
• Search stratigraphic namesFind stratigraphic names (supergroups, groups, formations, members and beds) that start with, contain or are exactly a name, by rank and age, each with its place in its hierarchy, age range, how many rock units carry it and its source.
• Get a stratigraphic nameGet one stratigraphic name by its ID, with its rank, age, source and every name in its hierarchy: the group it is in, the formations beside it and their members and beds. 'Found' is false when Macrostrat has no such name.
• Get a stratigraphic conceptGet a stratigraphic concept, which joins the names used for the same rocks, with its lexicon entry: its age, where the name comes from, the basins and provinces it is found in, usage notes, its names and a link to its source lexicon.
• Search the dictionaryFind anything in Macrostrat's dictionary whose name starts with some text: time intervals, stratigraphic names, columns, rock types, environments, economic uses, minerals and more, each with its ID for the action that reads it. Up to 100 matches.
• Look up a time intervalLook up a geologic time interval, such as the Permian or the Tremadocian: when it began and ended in millions of years, how long it lasted, its kind, its color on time scale charts, the eon, era, period and epoch it is part of, and its timescales.
• Find time intervals by ageFind the geologic time intervals at an age (which period was 100 million years ago?) or in a range of ages, on any timescale, or list a whole timescale: eons first, then eras, periods, epochs and ages, each youngest first.
• Look up a mineralLook up minerals by name, or the start of one, or by group, such as feldspar: each with its chemical formula, hardness, crystal system, colors, lustre and its mindat.org page.
