The first clue to the presence of possible diamond-bearing source rocks in northern Alberta was the discovery of a perfect octahedral diamond, estimated at about 0.83 carats in weight, by farm worker Einar Opdahl during 1958 in the Evansburg area of west-central Alberta. Since the Opdahl diamond, no new diamond finds were reported in northern Alberta until the 1990s, when several occurrences of alluvial diamond and diamondiferous kimberlite were discovered.

This Alberta diamond inclusion dataset includes electron microprobe analyses of garnet, clinopyroxene, olivine, ferropericlase and rutile inclusions from diamonds sampled by the Buffalo Head Hills kimberlite field. The data are compiled from Davies et al. (2004) and Banas (2006). Diamond inclusions are of particular research interest in diamond exploration and mantle petrology because they provide direct information about the chemical composition of upper and lower mantle and about the petrogenetic sources of diamonds in a given area/deposit.

Surveys include information related to diamond drilling.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This is the spatial view used by Mineral Titles Online (MTO) on the mineral, placer and coal viewers. The spatial view combines the polygon information with attribute information for each title. Contains sub-surface title data in British Columbia for: - mineral claims, mining leases, mineral claim applications - placer claims, placer leases, placer claim applications - coal license applications, coal licenses, coal leases

Determines the location of Coal Titles within the Province of British Columbia. It is established under the authority of the Petroleum and Natural Gas Grid Regulation. It is defined by a set of UTM coordinates which approximate NAD 27 latitude and longitude positions. Mapsheets are the coarsest component of the grid and approximate 1:250,000 NTS map sheets.

Determines the location of Coal Titles within the Province of British Columbia. It is established under the authority of the Petroleum and Natural Gas Grid Regulation. It is defined by a set of UTM coordinates which approximate NAD 27 latitude and longitude positions. Blocks are the second finest level of the coal grid. A block consists of 100 units divided into 10 rows by 10 columns. There are also 12 blocks in a group, comprising 3 rows by 4 columns and labelled A to L. E.G. 084E05L

Surveyed Placer Baselines are the mineral claim location lines. This consists of the lines required to establish the position for Mineral Claims. COGO attributes are associated to the lines and depict the adjusted framework of the Mineral Claim Location Line fabric. Mineral Claim Location Lines are only used in the Yukon Territory.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Orders in Council (OIC) are regulations or legislative orders in relation to and authorized by an existing Act. This table identifies Yukon lands withdrawn from disposal, usually by Territorial Order in Council. In Corporate Spatial Warehouse (CSW) data is split out into spatial views by Act under which orders are authorized. The tables are comprehensive and include both active and expired orders. Spatial views show only the active data.In this table and spatial views, Regulations by Order in Council (OIC) are spatially represented to provide clarity regarding Yukon lands withdrawn from disposal. Spatial data is viewed by the Act under which the order is authorized. Not all orders are for withdrawal, different levels of withdrawal are common and not detailed in GIS attributes. It is important to read OIC documents for specific details ( [https://legislation.yukon.ca/legislation/page_a.html](https://legislation.yukon.ca:443/legislation/page_a.html) ).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
