A common clastic sedimentary rock is shale, the most abundant of all sedimentary rocks. Shale forms when mud and clay harden. Because the clay sediments are extremely small, they settle out slowly. In fact, shale formations can take about 5 million years to form. ... The most common chemical sedimentary rock is limestone.

Starting with a marble specimen, it's hard to trace backward and know what the source rock was-- aside from the fact that its chemical composition was calcium carbonate. I think limestone beds are much, much more abundant than travertine deposits, so chances are that a given marble formation came from limestone.
