I'd say it's more likely jam than preserves.
From the innerweb'z:
Jam is a thick spread made from fruit juice, chopped, crushed, or puréed fruit, and sugar. ... Preserves are another thick fruit spread made from fruit cooked with sugar, but in this case, large pieces of the fruit, or the whole fruit (as in the case of berries), are suspended in a firm jelly or less-gelled syrupy base.
