Explosive materials such as
pumices, lapilli and ashes may be blown by volcanoes thousands of
kilometers around and fall in a sedimentary basin.
Erratic are all sorts or rocks transported by glaciers and abandoned
wherever the lower altitude will stop their front. Rivers also transport
materials from one basin to another. So does the wind.
Rocks of continental origin, such as sandstones, conglomerates etc. are all sedimentary rocks and may well contain igneous fragments.
