Crops and native vegetation cannot grow in these briny soils. These legacy brine pits may have been forgotten, but the salts that they contain are still seeping into the surrounding soils. These old, covered over, forgotten brine pits are termed “legacy brine pits”. Once covered or buried, the brine pit location is difficult to detect visually. After the brine reserve pit is no longer used, it is sometimes covered over with dirt or a liner. The brine pit water may contain salts, minerals, or toxic substances that can lead to brine contamination in groundwater. These impoundments are also known as evaporation pits or reserve pits. The default destination is /geomodel.Ĭlick OK or Apply to generate the vein model.A brine pit is a surface impoundment used to store or evaporate water used in the drilling, mining, or processing industries. In the Destination container field, optionally change where the output is to be saved. A smaller triangle size will result in a higher resolution model that better conforms to thinner domains. Surfaces-choose whether to generate surface representations of the hanging wall, footwall and/or middle of the vein, coloured with the specified colours.ĭata points-choose whether to generate point sets of the hanging wall, footwall and/or middle of the vein.Īt the bottom of the panel, set Triangle size to change the maximum triangle size on any generated surfaces. Vein solid-select this checkbox to generate a solid surface representation of the vein model. The third frame shows the resulting model if the interval is specified as being inside the surface, in which case it is ignored, and the surface is modelled on the trending drillhole intervals.Ĭonfigure which objects to generate on the Outputs tab: The model pinches in to honour the data exactly. The second frame shows the resulting model if the interval is specified as being on the surface boundary. The drillhole in the centre has a single, short interval which may be incomplete. The first frame shows several drillholes, with the target interval coloured yellow.

The diagram to the right will update to indicate the effect of your choice.Ĭonsider the example below.
#GEOMODEL SOLIDS HOW TO#
This is to account for cases where the drillhole data is incomplete, in which case you might like to ignore the interval.Ĭhoose how to classify matching intervals occurring at the top or the bottom of the hole, either as: Under Drillhole ends, you can control the modelling behaviour where intervals of the target value occur at the top or the bottom of a drillhole. Relimit to polygon-the model will be extend laterally to the shape of the supplied polygon in the XY plane.Įxtrapolation distance allows you to extrapolate the model past the relimit constraints set above by the specified distance. Relimit to input data-the model will extend laterally to the shape of a convex polygon fitting the input data in the XY plane.

No relimiting-the model will extend laterally to fill a rectangular area aligned to the X and Y axes, roughly covering the extent of the input data. Under Relimiting, choose one of the following options: Under Extent limits, you can configure the limits of the model in the XY plane. To configure additional controls, switch to the Controls tab. Show trend plane-select this checkbox to show a transient trend plane in the view.įlip the hanging wall and footwall-select this checkbox to invert the meaning of the hanging wall and footwall.Ĭhoose a colour for the hanging wall and the footwall from the Hanging wall and Footwall colour pickers.Īdditional controls are available to constrain the vein model in various ways. Under Footwall data, specify any number of objects representing the footwall.Ĭonfigure the remaining options as follows: Under Hanging wall data, specify any number of objects representing the hanging wall. Only the points extracted from these objects will contribute to the model. The CAD data can be any object containing points, such as point sets, lines, or polygons. You can supply CAD data representing hanging walls and footwalls. Then, select the checkbox for the value from the Horizon column.

If there is a compatible legend for the variable you want to model, make sure it is specified under Legend. Type the name of the value in Value to model. To model your domains, select Intervals Table:Domain. įrom the Variable to model drop-down, select the table and field for the variable you want model. Remove an item by selecting it in the list and clicking. Alternatively, drag and drop the drillhole database or selection directly from the project explorer into the drillhole list. This field requires a drillhole selection from a single database.Īdd a drillhole database or drillhole subset to the list by making a selection in the project explorer and then clicking.
