“…Measuring the residence times of organic matter of such soils would allow us to refine the radiocarbon chronology, the next task being the construction of chronosequences focused on pedogenic attributes that evolve on timescales of 10 2 -10 3 a, often before the differentiation of B horizons. If this can be achieved, they may offer many advantages over the soils that develop on slopes (see Sedov et al, 2001Sedov et al, , 2003, including the good preservation of A horizons, as well as rapid and effective burial minimising pedogenic overprinting.…”

Fluvial response to Holocene climate change in low‐order streams of central Mexico

Alluvial sequences constitute a recognised source of information on past environmental change, but one that has scarcely been tapped in central Mexico. This paper reviews what is currently known about the Holocene alluvial stratigraphy of the region, focusing on the interplay between climate and the pace and style of sedimentation in the incised headwater reaches of stream networks. The records obtained in five different drainage basins -four in the state of Tlaxcala and one in Guanajuato -are presented and compared to published reconstructions of climate change. A nearsynchronous incision of all stream networks occurred close to 10 200 14 C a BP in response to an increase in precipitation and stream discharge. A spell of very humid but markedly seasonal conditions ensued, resulting in the formation of wet meadows along streams and the accumulation of thick finetextured valley fills dominated by cumulic soil A horizons. After 9100 14 C a BP a transition to a warmer and more arid climate provoked the thinning of vegetation cover on slopes, accelerated runoff and increased sediment delivery to streams. The aggradation of coarser-textured valley fills poor in organic matter set in. It ceased or slowed down significantly after a few millennia as the studied stream reaches achieved a near-graded condition adjusted to the relatively stable climate. Arid mid Holocene conditions are also reflected in the abundant precipitation of secondary carbonates in Guanajuato. At 3100 14 C a BP higher precipitation caused more frequent flooding and a resumption of aggradation. Shortly after that date sedentary farmers colonised Tlaxcala. Agriculture altered runoff and sediment delivery to streams and accelerated cut-and-fill cycles on a scale that masked the impact of any climatic fluctuations. Guanajuato was colonised later and its alluvial record suggests the persistence of a humid climate at least until 1000 14 C a BP.

“…As dispersed assemblages in the sedimentary record they are used to interpret the nature of contemporaneous vegetation and climate (e.g., Carter 2002;Strömberg 2002;Delhon et al 2003;Sedov et al 2003;Thorn 2004a). Phytoliths vary in morphology, size, and surface texture, are usually solid, and may contain carbonaceous inclusions of remnant cell wall material (Piperno 1988;Pearsall 2000).…”

Phytoliths are microscopic particles of opaline silica (SiO 2 .nH 2 O) formed by the accumulation and solidification of siliceous gel between and within the cells of many plants. Soil surface phytolith assemblages are assessed for their potential to accurately reconstruct the overlying vegetation community within the subalpine zone of Tongariro National Park, New Zealand. The results provide important new evidence that phytoliths are an under-exploited tool for reconstructing past vegetation patterns. A new technique has been developed to quantitatively compare phytolith supply with accumulation. From four study sites, plants and soil were collected for phytolith extraction, and vegetation height and canopy cover were surveyed. The results indicate that at three of the four sites, source vegetation could be satsifactorily reconstructed at a broad community level from the dispersed soil phytolith record implying similar expectations for the application of this technique to the fossil phytolith record.
