Description: Displays the location of field sites where geological information has been gathered. Observations made at these sites include descriptions of outcrops (including rock types and structures), mines, mineralisation or fossil localities. Samples may have been collected from these sites for further study, such as petrography, chemical analysis or isotopic dating. Some sites have been digitised from previously published or unpublished maps and the structural data recorded at these sites captured into the database.
Description: <DIV STYLE="text-align:Left;font-size:12pt"><DIV><P><SPAN>This data set displays the locations and orientations of selected primary structures that have been measured during field studies. Primary structures are features of rocks that form at or shortly after the time of formation of the rock itself. In this data set, only planar features are shown, such as bedding in sedimentary and volcaniclastic rocks and primary igneous structures such as flow banding in lava, eutaxitic foliation in ignimbrite and alignment of minerals by platy flow or compositional layering in plutonic rocks. </SPAN></P></DIV></DIV>
Description: This data set displays the locations and orientations of selected tectonic structures where these have been measured during field studies. Tectonic structures are those that develop in rocks after their formation as a result of their subjection to tectonic forces. In this data set, only planar features such as foliations and cleavage or linear features such as stretching lineations, intersection lineations, crenulations and mineral alignment that can be easily symbolised are included.
Description: This data set displays the location of all field sites where the orientations of primary and tectonic structures have been measured during field work. Some sites have also been digitised from previously published or unpublished maps and the structural data recorded at these sites captured into the database. In addition to the features shown in the Primary Structures and Tectonic Structures layers, this dataset includes all other measurements made. These include primary structures such as paleocurrent indicators like cross-bedding, ripple marks and parting lineations. It also includes other tectonic structures such as fold axes and axial planes, joints and faults.
