stable isotopes of oxygen (δ18o) and carbon (δ13c) are recorded well in speleothems, giving high-resolution data that can show annual variation in temperature (oxygen isotopes primarily reflect rainfall temperature) and precipitation (carbon isotopes primarily reflect c3/c4 plant composition and plant productivity, but the interpretation is often complicated).
