Grenville, Gibson Road East, Titanite, Microcline, Fluorapatite, Phlogopite

The occurrences at Gibson Road East are a continuation of the calcite vein-dyke trend that we used to collect at the "Bear Lake Diggings". The mineralization and mode of occurrence is similar; calcite vein-dykes with fluorapatite in the calcite and the other minerals mostly occurring on the wall rock of the contact between the vein dykes and the country rock. There are lots of places to look on the Crown Land in the area. Here are some nice examples.

  • A pleasant looking, lustrous, light green doubly terminated fluorapatite crystal that has been etched out of calcite, naturally, by groundwater. The crystals is solid and shows areas where the crystal has started to diverge/divide. Interesting and attractive crystal!

  • This specimen features a couple of parallel growth crystals that are terminated at the top ends but poorly terminated on the bottom. It appears that the bottom actually was a fractured and re-healed surface. The crystals has light green colour and has good luster on four of the six faces. Interestingly, the crystal has a thin quartz veinlet that cuts through the crystal slightly below the termination. Nice crystal!

  • A prismatic, elongated twinned crystal of fluoro-richterite. The crystal is terminated on the top with all the faces present but faitly rounded. The bottom is also terminated, showing the twin re-entrant angle but it is a very rough contact termination. This is an impressive prismatic amphibole crystal.

  • A fairly handsome cluster of crystals that appears to be a true "floater". There is no obvious point of attachment. The sharp crystals have very good luster and on the back side, there are lots of small apatite crystals that disrupt the nice luster plus one bigger apatite.

  • Here is an interesting crystal! It almost appears like a sceptered crystal at first glance but it really is not. The main crystal has, somehow developed several offset crystals. not parallel but close on the termination and, as you can see, also on the back of the crystal. Interesting morphology!

  • This specimen shows a very nice, lustrous, well formed titanite crystal perched atop a cluster of not-so-great microcline crystals, mostly contacted. Still the titanite is highly lustrous with the typical dark brown colouration and wedge-shape. Looks good!

  • A larger, green fluorapatite crystal showing typice Grenville internal fracturing. It is a doubly terminated crystal showing a good termination on one end dominated by a single pyramidal face and a more rough, incoherent termination on the bottom end. Feels and looks great!

  • This specimen is solid titanite, one central crystal attached to two thick titanite crystal sections. The central totanite crystal looks perfect at first glance but, in fact, the outer edge is well abraded. Not perfect despite looking so! Displays very well!

  • A large, half crystal of titanium silicate. Heavily abraded around the edges. Sorry, didn't take a picture of the back but it is essentially the same as the front. It is fairly impressive and solid.
