This file should be accompanied by EmmitsburgGeMS.gdb-ValidationErrors.html, EmmitsburgGeMS.gdb-vFgdcMetadata.txt, and EmmitsburgGeMS.gdb-vFgdcMetadataErrors.txt, all in the same directory.

This database is LEVEL 2 COMPLIANT, pending completion of a peer-reviewed Geologic Names report that includes identification of any suggested modifications to Geolex. The database-level FGDC metadata are formally correct. The metadata record should be examined by a human to verify that it is meaningful.

Glossary

OBJECTID	Term	Definition	DefinitionSourceID	_ID
16	bedding	The arrangement of sedimentary rocks in beds or layers of varying thickness and character; the general physical structural character or pattern of the beds and their contacts within a rock mass, such as cross-bedding and graded bedding; a collective term denoting the existence of beds. Also, the structure so produced. The term may be applied to the layered arrangement and structure of an igneous or metamorphic rock.	DS02	GLID18
1	certain	Identity of a feature can be determined using relevant observations and scientific judgment; therefore, one can be reasonably confident in the credibility of this interpretation.	FGDC-STD-013-2006	GLID01
17	cleavage	A locally planar fabric in an unmetamorphosed or weakly metamorphosed, fine-grained rock defined by either the tendency of a rock to split in a particular direction, a preferred orientation of crystal planes in mineral grains, or a preferred orientation of inequant grain shapes; it is a produce of deformation or metamorphism.	DS02	GLID19
18	Contact	A plane or irregular surface between two types or ages of rock; examples are faults, intrusive borders, bedding planes separating distinct strata, and unconformities.	DS02	GLID20
19	Fault	A discrete surface or zone of discrete surfaces separating two rock masses across which one mass has slid past the other.	DS02	GLID21
20	fold axis	A line which, when moved parallel to itself, traces out a folded surface. It applies only in the case of cylindrical folds.	DS02	GLID22
21	foliation	A general term for a planar arrangement of textural or structural features in any type of rock, esp. the locally planar fabric in a rock defined by a fissility, a preferred orientation of crystal planes in mineral grains, a preferred orientation of inequant grain shapes, or from compositional banding. In igneous rock, planar parallelism of flaky or tabular mineral and mineral aggregates, slabby xenoliths, or flattened vesicles as well as compositional layering. Inmetamorphic rocks, planar parallelism of flaky minerals and compositional layering.	DS02	GLID23
12	Header1	Formation header, bolded text, no indent. This format is used for Formations, Quaternary deposits, and basement complex.	DS01	GLID11
13	Header2	Member header, bolded text, indented. This format is used for named members (e.g. Dargan Member, under Tomstown Formation) and for sub-units without proper names (e.g. Phyllite, under Swift Run Formation).	DS01	GLID12
14	Header3	Group header, bolded text, capitalized, no indent.	DS01	GLID13
15	High	High level of confidence that GeoMaterial term accurately and appropriately describes the map unit.	FGDC-STD-013-2006	GLID14
22	joint	A planar fracture, crack, or parting in a rock, without shear displacement; the surface is usually decorated with a plumose structure. Often occurs with parallel joints to form part of a joint set.	DS02	GLID24
11	lineation	A general, nongeneric term for a locally linear structure or fabric in a rock, e.g. flow lines, scratches, striae, slickensides or slickenfibers on a single surface; linear arrangements of components in sediments; or axes in folds. Lineation in metamorphic rocks include aligned rod-shaped and/or elongate minerals grains, crenulation fol axes, and the lines of intersection between bedding and cleavage or any two sets of oriented surfaces.	DS02	GLID9
23	pit, hand dug	Pit - definition (b) A shallow excavation, up to several meters depth, dug to expose a soil or geologic section of relative soft sediments.	DS02	GLID29
2	questionable	Identity of a feature cannot be determined using relevant observations and scientific judgment; therefore, one cannot be reasonably confident in the credibility of this interpretation. For example, IdentityConfidence = questionable is appropriate when a geologist reasons "I can see some kind of planar feature that separates map units in this outcrop, but I cannot be certain if it is a contact or a fault."	FGDC-STD-013-2006	GLID02
