This database may be LEVEL 1 COMPLIANT.
The metadata record for this database has formal errors. Please fix!
This file should be accompanied by CT_HartfordBasinBedrock.gdb-ValidationErrors.html and CT_HartfordBasinBedrock-metadata.xml_errors.txt in the same directory.
If this database will be submitted to the NGMDB, it also needs to be accompanied by a reviewed Geologic Names report that includes identification of any suggested modifications to Geolex. Use the Geologic Names Check tool to generate that report or provide other documentation of a review.

### Compliance Criteria

#### LEVEL 1

Criteria for a LEVEL 1 GeMS database are:

- No overlaps or internal gaps in map-unit polygon layer
- Contacts and faults in single feature class
- Map-unit polygon boundaries are covered by contacts and faults lines

Databases with a variety of schema may meet these criteria. This script cannot confirm LEVEL 1 compliance.

#### LEVEL 2--MINIMALLY COMPLIANT

A LEVEL 2 GeMS database is accompanied by a peer-reviewed Geologic Names report, including identification of suggested modifications to Geolex, and meets the following criteria:

2.1 Has required elements: nonspatial tables DataSources, DescriptionOfMapUnits, GeoMaterialDict; feature dataset GeologicMap with feature classes ContactsAndFaults and MapUnitPolys | PASS
2.2 Required fields within required elements are present and correctly defined | PASS
2.3 All MapUnitPolys and ContactsAndFaults based feature classes obey Level 2 topology rules: no internal gaps or overlaps in MapUnitPolys, boundaries of MapUnitPolys are covered by ContactsAndFaults | FAIL multiple topology errors
2.4 All map units in MapUnitPolys have entries in DescriptionOfMapUnits table | PASS
2.5 No duplicate MapUnit values in DescriptionOfMapUnit table | PASS
2.6 Certain field values within required elements have entries in Glossary table | PASS
2.7 No duplicate Term values in Glossary table | PASS
2.8 All xxxSourceID values in required elements have entries in DataSources table | PASS
2.9 No duplicate DataSources_ID values in DataSources table | PASS

#### LEVEL 3--FULLY COMPLIANT

A LEVEL 3 GeMS database meets these additional criteria:

3.1 Table and field definitions beyond Level 2 conform to GeMS schema | PASS
3.2 All MapUnitPolys and ContactsAndFaults based feature classes obey Level 3 topology rules: No ContactsAndFaults overlaps, self-overlaps, or self-intersections. | PASS
3.3 No missing required values | PASS
3.4 No missing terms in Glossary | PASS
3.5 No unnecessary terms in Glossary | PASS
3.6 No missing sources in DataSources | PASS
3.7 No unnecessary sources in DataSources | PASS
3.8 No map units without entries in DescriptionOfMapUnits | PASS
3.9 No unnecessary map units in DescriptionOfMapUnits | PASS
3.10 HierarchyKey values in DescriptionOfMapUnits are unique and well formed | PASS
3.11 All values of GeoMaterial are defined in GeoMaterialDict. GeoMaterialDict is as specified in the GeMS standard | PASS
3.12 No duplicate _ID values | PASS
3.13 No zero-length, whitespace-only, or bad null values | PASS

### Warnings

There are 2 warnings

### Content not specified in GeMS schema

Some of the extensions to the GeMS schema identified here may be necessary to capture geologic content and are entirely appropriate. Please document these extensions in metadata for the database, any accompanying README file, and (if applicable) any transmittal letter that accompanies the dataset. Other extensions may be intermediate datasets, fields, or files that should be deleted before distribution of the database.

#### Glossary

OBJECTID | Term | Definition | DefinitionSourceID | Glossary_ID

3 | Bedding | The arrangement of sedimentary rocks in beds or layers of varying thickness and character; the general physical and 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. | DAS26 | GLO02
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. | DAS25 | GLO01
47 | Columnar Joint | Parallel, prismatic columns, polygonal in cross section, in basaltic flows and sometimes in other extrusive and intrusive rocks. It is formed as the result of contraction during cooling. (May include measurements of intersecting joints. Trend and plunge measured.) | DAS26 | GLO23
9 | 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. | DAS26 | GLO07

42 | Elevation profile | Line representing ground surface elevation on geologic cross sections. | DAS01 | GLO19
10 | Fault | A discrete surface or zone of discrete surfaces separating two rock masses across which one mass has slid past the other. | DAS26 | GLO08
40 | geochemical sample | One or several pieces of whole or split parts of a rock or core, selected for geochemical analysis. | DAS27 | GLO17
36 | High | The selected term in the GeoMaterial field (and its definition) adequately characterizes the overall lithologic nature of rocks and (or) sediments in the map unit. | DAS28 | GLO16
11 | High-Angle Fault | A fault with a dip greater than 45 degrees. | DAS26 | GLO09
5 | Inclined Feature | Feature within igneous rock unknown. At an angle between 1 and 89 degrees. | DAS01 | GLO04
6 | Inclined 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 fissility, a preferred orientation of crystal planes in mineral grains, a preferred orientation of inequant grain shapes, or from compositional banding. In igneous rocks, planar parallelism of flaky or tabular minerals and mineral aggregates, slabby xenoliths, or flattened vesicles as well as compositional layering. In metamorphic rocks, planar parallelism of flaky minerals and compositional layering. At an angle of 90 degrees. | DAS26 | GLO05
45 | Inclined Joint | [struc geol] A surface of fracture or parting in a rock, without displacement; the surface is usually plane and often occurs with parallel joints to form part of a joint set. (Inclined. Strike and dip measured.) | DAS26 | GLO21
13 | map boundary | The outline or boundary of the geologic units (or lack thereof) composing the state of Connecticut, as digitized from the Rodgers 1985 bedrock map publication. | DAS03 | GLO10
8 | 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” would be 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” | DAS25 | GLO06
41 | tic | Short horizontal lines on the ends of the cross sections, representing depths (relative to sea level) marks in feet and meters. | DAS01 | GLO18
4 | Vertical Feature | Feature within igneous rock unknown. At an angle of 90 degrees. | DAS01 | GLO03
46 | Vertical Joint | [struc geol] A surface of fracture or parting in a rock, without displacement; the surface is usually plane and often occurs with parallel joints to form part of a joint set. (Not inclined. Strike and dip measured.) | DAS26 | GLO22
