Mines and Mineral Occurrence Sites

Sites where earth resources have been demonstrated. This includes metallics, industrial minerals and construction materials, but excludes oil, gas and groundwater resources which are recorded in OILGAS and BORES datasets. OILGAS will be available for external users within Petroleum Mapshare. It is thought that groundwater resources will be available to external users within a CLPR (Catchment and Land Protection) Mapshare View. \n\nThe data is derived from Minerals and Petroleums RDBMS, which is known as VICMINE.\nInformation on each site has been compiled mostly from historical literature, with only selected major sites visited in the field.\n\nNOTES CONCERNING GEOVIC "Mines and Mineral Occurrence" DISPLAY\n-----------------------------------------------------------------------------------------------------------------------------\nThe type of mine/mineral occurrence displayed varies with the scale of the map view.\nMajor and Intermediate size mines are displayed at all scales.\nMinor and Unknown size Mines are displayed at scales ranging from 1:1 to 1:500,000\nMAJOR is for mine_size greater than= 85000000\nMINOR is for mine_size less than 8500000\nINTERMEDIATE is for mine_size between the two\nUNKNOWN is when the mine_size is unknown\n\nMINE_SIZE (better name would be MINE_VALUE) is a calculated dollar amount based on the total production and resource for each commodity multiplied by the commodity price (NOTE: these commodity prices have not been updated in some time eg: as of 13/1/2013 the gold price per ounce used was $526.70 - April 1985 prices) \n\nNOTES CONCERNING GEOVIC "Deposit Styles" DISPLAY\n-----------------------------------------------------------------------------------------------------------------------------\nA number of deposit style layers exist in GeoVic.\nThe layers are based on particular values of the dep_style attribute - within this dataset.\nThe dep_style attribute contains the results of classifying the mineral deposits of Victoria east of approximately 142°30' and west of 145°30', but excluding the Willaura (7422) 1:100 000 map sheet area. The classification is described in detail in Moore, D.H., 2007. "Classifying gold deposits in central and western Victoria, Australia. GeoScience Victoria Gold Undercover Report". \n\nGENERAL NOTES CONCERNING GEOVIC\n-----------------------------------------------------------------------------------------------------------------------------\nRefer to Mineral Regions 1M (MINERAL) for extent of brown and black coal fields, Heavy Mineral Sands 1M (MINSAND1M) for extent of strandline mineral sand deposits, and Heavy Minerals Sands WIM 1M (MINSAND1M) for extent of WIM style mineral sand deposits.

已证实存在地球矿产资源的点位。本数据集涵盖金属矿产、工业矿物与建筑材料，但不包含石油、天然气及地下水资源——此类资源分别记录于OILGAS与BORES数据集。OILGAS将通过Petroleum Mapshare向外部用户开放。据悉，地下水资源将通过CLPR（Catchment and Land Protection，流域与土地保护）Mapshare视图向外部用户开放。

本数据集源自名为VICMINE的矿产与石油关系数据库管理系统（Relational Database Management System, RDBMS）。各点位的信息主要来源于历史文献，仅对部分重点点位开展了野外实地核查。

关于GeoVIC"矿山与矿产产地"展示的说明
-----------------------------------------------------------------------------------------------------------------------------
展示的矿山/矿产产地类型随地图视图的比例尺变化而有所差异。大型与中型矿山在所有比例尺下均会显示。小型及未知规模的矿山仅在1:1至1:500000的比例尺范围内显示。
MAJOR 对应矿山规模值（mine_size）≥85000000
MINOR 对应矿山规模值＜8500000
INTERMEDIATE 对应矿山规模值介于上述两者之间
UNKNOWN 对应矿山规模值未知

MINE_SIZE（更合适的命名应为MINE_VALUE，即矿山价值）为计算所得的金额，其计算逻辑为：各商品的总产量与资源储量分别乘以对应商品的市场价格。（注：此类商品价格已有较长时间未更新，例如截至2013年1月13日，所使用的黄金每盎司价格为1985年4月的526.70美元）

关于GeoVIC"矿床类型"展示的说明
-----------------------------------------------------------------------------------------------------------------------------
GeoVIC中包含多个矿床类型图层。本数据集内的图层基于dep_style属性的特定取值构建。dep_style属性包含了维多利亚州约142°30′以东、145°30′以西区域（不含Willaura（7422）1:100000图幅范围）内的矿产矿床分类结果。该分类方法的详细说明参见Moore D.H.于2007年发表的《澳大利亚维多利亚州中西部金矿床分类》（GeoScience Victoria金矿隐伏报告）。
