![]() The ratios Nb/Ta (7.7 - 17.7) and Zr/Hf (16.9 - 26.4) are relatively enriched in the lighter isovalents Ta and Hf. U-enrichment associated with chloritization, muscovitization, albitization, sericitization, kaolinization and argillization results from convective hydrothermal circulation of fluids through brittle structures along the ENE-WSW main shear zone. They are enriched in large ion lithophile elements (LILE Ba, Rb and Sr), high field strength elements (Y, Zr and Nb), and LREE but depleted in HREE with negative Eu anomaly. Geochemically, two-mica granite boreholes are A-type granites and peraluminous characteristics. Chlorite, muscovite, sericite, kaolinite are secondary minerals. Accessories are pyrite, zircon, fluorite, rutile, monazite with Th-U-mineralization identified by scanning electron microscope (SEM) and electron probe-microanalyses (EPMA). They are composed of K-feldspar, plagioclase, quartz, biotite and muscovite. Microscopically, the three boreholes are composed mainly of two-mica granite. From the about window you can use the 'Check for Updates' facility and also access the Preferences, which is where you can set the default magnification pointer size and also enter your name and serial number.The present work aims at identifying Nb-Ta-, Zr-Hf-, REE-, Th-U-bearing two-mica granite from geological, geophysical cross-sections and mineral chemistry studies from three boreholes at G. Selecting the P+ Menu from the Status menu gives you mouse access to the above functionality and also the ability to access the About window and to Quit the program. Shift + Ctrl + S: This key combination saves the contents of the magnify cursor to the desktop as a Jpg. The default size in pixels can be set from the Preferences screen and the size can be between 200 and 800 pixels. To close the magnify cursor, use the same key combination. This facility is again very useful when demonstration something to another. Click in the circle to drag it to a new position, when you release the mouse the new position will be magnified. Shift + Ctrl + Return: This key combination creates a large circle in the middle of the screen and magnifies the contents of that circle. To switch off the pointer use the same key combination. Every time you click the mouse the circle pointer is made larger and bolder for a second and a cross-hair target is overlaid on the mouse position. Once you click the mouse this enhanced pointer will overlay your mouse cursor and follow it's every move, providing much greater visibility to the cursor. Once running Pointer+ gives you three extra 'Hotkey' options: Shift + Ctrl + P: This key combination adds a small black circular surround to the middle of the screen. Pointer+ is shown as P+ in the Status Bar. ![]() When running Pointer+ it installs itself in the Status Bar Menu, to the top right of the screen near the Clock and Spotlight. Functionality that is invaluable if you are using your computer to demonstrate software to a third party, or if using any sort of screen recording software. Pointer+ is a simple, very focused application for your Mac that adds additional functionality at the press of a key.
