February-March 2022 Fossicking Trip: Stone of the Day #8, Gemstone Beach Red Stone With Orange Shapes

I spent 3 1/2 hours on Gemstone Beach today, arriving at 9.30 am. and walked maybe half a kilometre past the Waimeamea River lagoon. The weather was good, being partly cloudy and warm. However, the lack of bright sunlight made photographing individual stones difficult at times, with reflections marring the stone’s surface. I found today’s Stone of the Day towards the end of my fossick:

Stone of the Day #7

One possibility for the origin of the orange shapes is that this stone is amygdaloidal, with original vesicles (small holes) being in-filled as water moved through them over a long period of time, minerals precipitating out.

The tide was low again when I arrived at Gemstone Beach.

Some of the other stones I collected today to take home to tumble polish – the first two are banded argillites, one small and one medium sized:

Larger banded argillite.

Four “textured” stones of different colours:

I find a number of the black and white stones quite attractive.

An interesting texture.

Could be orbicular.

Finally, one small stone with interesting black markings, and a nice dark green hydrogrossular garnet:
