I decided to remove the tiles in my front courtyard and turn it into a garden of succulents. After removing a couple of rows of tiles then digging into the soil, I started seeing a strange thick white clay like substance like melted marshmallows. I figured it was obviously clay. But the deeper I dug, I started to see lots of very vivid colours: very dark red, almost purple, yellows, oranges greys, pinks, blood reds + some dark green. I know sandstones have all sorts of colours due to its make-up of quartz etc - but this was very different.
I started to think there was some sort of large animal buried there as that's what it looked like especially with all the reds and pinks and the white substance which there was loads of.
I kept seeing long stringy "fibres" thinking it was from a tarpaulin or plastic bag. BUT.. no. then I thought it was very fine roots from old plants. NO. there also appears to be 100s if not 1000s of tiny microscopic "white worm" things.
What could do this to sandstones or any rock? Turning big sandstones into a very thick stretchy heavy substance which is almost impossible to get off your shovel or gloves or any tool? And there's an enormous amount of this.
There's also a large number of tiny black things embedded into the gooey sandstone.
I am very concerned about what's happening. I bought my place in June 2019. Moved in December 2019. So been here just on a year.
I live very close to the city of Sydney. I don't think its the Rock Eating Worm/Shipworm- but I don't know.
Any help is greatly appreciated.
