I spent just over two hours on Seadown Beach today, at low tide. It was cloudy, 12 degrees, but no wind. When I arrived, there were four surfers there – Mum and Dad and two young teens, I think. I was able to walk south and investigate a number of small bays among the rocks. I went at least one bay further than I have gone before, searching the small patches of stones to be found there. At one point, I encountered a mass of insects on the rock cliff. When I got within a metre of them, they flew up and buzzed at my head until I withdrew. I initially thought they were sandflies but they were a little larger and more aggressive than I normally associate with that insect.
To turn to ten of my finds today. I kept a lookout for the brown stone that contains tiny fossils like bryozoa. Sometimes it’s not easy to get a clear idea whether there are fossils in such a stone or not. I found the two following specimens that looked to have the right rock material but I cannot clearly identify fossils in them:
A gorgeous green quartzite, that looks to have epidote in it:
The next two finds featured in today’s Post are small red stones, one jasper and one quartzite. The jasper has a lot of detail in it:
The hues in the quartzite range from orange to red:
A couple of limestone pebbles, the first with numerous tiny fossils, the second with a couple of fossil rhodoliths in it:
Finally, three quite different yellow-brown stones with interesting patterns:
Part 30 covers my last fossick on Kakanui’s Seadown Beach for this trip. An Index to this Series is here.
