  abstract = {{S}ilicon ({S}i) is the second most abundant element on {E}arth after oxygen. {O}nly few studies have attempted to use stable isotopes of {S}i as proxies for understanding the {S}i cycle and its variations in the past. {B}y using three different methods ({IRMS}, {MC}-{ICP}-{MS} and {SIMS}), the overall measurements show that the isotopic composition (delta {S}i-30) of terrestrial samples ranges from -5.7 parts per thousand to +3.4 parts per thousand. {D}issolved {S}i in rivers and seawater is {S}i-30-enriched (-0.8 parts per thousand < delta {S}i-30 < +3.4 parts per thousand) compared to {S}i in endogeneous rocks (-1.1 parts per thousand < delta {S}i-30 < +0.7 parts per thousand). {T}his global enrichment is counterbalanced by the {S}i-bearing phases (biogenic silica, clays, quartz) where {S}i is, in average, {S}i-30-depleted (-5.7 parts per thousand < delta {S}i-30 < +2.6 parts per thousand). {T}hese values are the result of fractionation which have been measured or estimated from -0.3 parts per thousand to -3.8 parts per thousand. {T}he fractionation is modeled by two types of approaches: the {R}ayleigh distillation model (closed system) and the steady-state model (open system). {T}hese models have been used in the most recent studies to explain the observed delta {S}i-30 variations in continental environments and in the sub-{A}ntarctic {O}cean.
