Looks to me like you've got a mixture of stromatolite (most evident in first photo), quartz crystals and limonite?
Edit - On closer inspection, I don't think it is a stromatolite. It almost has a rhyolite look to it, but I'm not sure. The limonite is an iron ore, so that would make it feel heavy for its size.
