It's killing me that I don't know what it is I'm finding since I know that I have to choose a few pieces to keep at the end of our trip. So I'm hoping some one could help with some ID. We are currently at the Ventura Beach CA and I found these today, i really loves the patternes. 1. Unknown but possible sandstone 2.
3. 4.Think this is an agat? 5. Dark red/Brown ? 6. Green one 7. Red with White thin lines 8. Black and White stuff 9. This one I know is a poppy Jasper and I'm so happy I found it. 10. The last one and it has really Strange colours, looks like red/green/blue but it's not so strong in the colours Really hoping someone can help with ID since we are staying here for a couple of days and i want to go and find more of the good stuff.

7 might just be a regular red jasper with veins of quartz, will polish well. As for number five... if it is an amphibole, I'd say it's hornblende? Plenty of that to go around in the desert.

I used to live in Ojai and hound the beaches at the Ventura rivermouth. Found a lot of similar stuff although the poppy jasper is much commoner further north towards Santa Barbara and Gaviota. Forst tow are probably banded sandstone or if more conpressed and replaced by silica, quartzite. Lots of that in many colors in those gravels. #4 is an agate nodule. There are agate beds inn the volcanics south of Ventura and east of Camarillo and out at Somis. Your stone probably came down Callegues Creek or the big creek through Somis and was transported by longshore drift. #5+6 possible andesite from the volcanic deposits south of Camarillo. #7 plain ole brown jasper or chert #8 and 10 quartzite. Watch for good fossil agatized whalebone, good brecciated jasper and sinter too. All those are great cutting material....Mel

Don't know if we have time, but maybe we can make a meetup of RTH members in LA area.

As for number five... if it is an amphibole, I'd say it's hornblende? Plenty of that to go around in the desert. We find lots of rocks around Lake Michigan that look like #5. Around here they're called Porphyry. Porphyry has been used for eons as a sculpture media. Not saying that is what you have for sure though. But you did mention it was red to brown. When wet my porphyry looks dark like yours. As to it being hornblende, I think most if not all hornblende is black like what you find in granite. I find the occasional piece of pure black hornblende. That is the stuff they use for black granite counter tops. Below, porphyry: Below, porphyry sculpture: Below, hornblende: Hornblende has a hardness of 5–6, a specific gravity of 2.9–3.4 and is typically an opaque green, greenish-brown, brown or black color.
