Carbon**ate** deposits, not carbon deposits.
That’s interesting, because the biggest carbonate deposits on Earth are insoluble calcium carbonates formed by living aquatic organisms that produced calcium carbonate shells. However, they can also form as evaporite or hydrothermal deposits.
Curiosity found rocks containing an iron carbonate mineral, siderite. It did not find large carbon deposits.
