Conglomerate is the name of one type of rock, which is formed from a mixed source. The source rocks are commonly rounded pebbles. Often quite beautiful. And of course, the type of source rocks may be easily determined. Such a rock obviously originates from re-worked young gravels, - probably fresh water.
There is another common type of sedimentary rock, formed in marine shelf areas. Upon the shelf edge collapsing, some of the recent clays and silts will tear loose some of the more indurated older formation. The older rock is usually quite angular and is well cemented in the younger material. [Sorry - I forget the name!]
Quite differently, will be intrusive sills and dikeswhich will usually be either volcanic or granitic. You'll be able to spot the chilled margins of the intrusive - and the slightly re-heated margin in the host rock.
