Mulu Borneo stalagmite SC02 d18O and d13C 19.5-10.7 ky BP
<p>Here are presented Mulu, Borneo (4°6’N, 114°53’E) Secret Cave stalagmite SC02 d18O and d13C values over Termination 1, published in Buckingham et al. (accepted). U-Th ages were calculated using the initial detrital 230Th/232Th value of 111 ± 41 ppm. A Matlab Monte Carlo script was used to calculated the absolute age and age errors associated with each U-Th sample. The Poisson-process deposition model feature in OxCal(v4.4) was used to interpolate between the eighteen U/Th ages to produce an age model. This study reports a d18O and d13C record for the portion of SC02 104.1 to 182.4 mm distance from top of stalagmite. The d18O record spans the full deglaciation, and reveals distinct d18O variations connected with the Bølling-Allerød onset and the Younger Dryas event.</p>
Shihua cave stalagmite CS01C d18O, d13C, lamina thickness, and stalagmite SHD1311 d18O during early Holocene 11.3 - 10 ka BP
<p>Here we present results of <sup>230</sup>Th dating, stable isotope and lamina thickness data from two stalagmites (CS01C and SHD1311) from Shihua Cave (latitude 39´47°N, longitude 115´56°E; altitude 251 m a.s.l. at the entrance), northern China, during 11.32 to 10 ka BP. CS01C developed with clear annual lamina. The age model of CS01C is based on lamina counting. The age model of SHD1311 is established using the COPRA algorithm. The variability of stalagmite δ<sup>18</sup>O records is interpreted as a proxy of regional summer monsoon precipitation and/or EASM intensity. Stalagmite δ<sup>18</sup>O records show two weak summer monsoon events at 10.9 and 10.3 ka. The 10.9-ka event occurred from 10.93–10.79 ka BP for ~140 yr and features a “W”-shaped structure. The 10.3-ka event, also known as the ice-rafted debris event 7 in the North Atlantic, lasted ~260 yr with an asymmetric double-plunging structure.</p>
Data for Klaes et al. High-resolution stalagmite stratigraphy supports the Late Holocene tephrochronology of southernmost Patagonia. Comms. Earth Environ. (2022)..
<p>This data set comprises the LA-ICP-MS, ICP-MS, EPMA and NanoSIMS measurements as well as SEM imagery presented in the research paper 'High-resolution stalagmite stratigraphy supports the Late Holocene tephrochronology of southernmost Patagonia' by Klaes et al. The Th-U data of the revised chronology of stalagmite MA1 with the calculated correction values according to Budsky et al. (2016) are also included. In addition, stable isotope data from Schimpf et al. (2011) with the revised version of the age-depth model are given. For detailed information on the analyses (e.g., instruments used), the user is kindly referred to the methods section of the article. </p>
Variation of the Asian summer monsoon since the last glacial-interglacial recorded in a stalagmite from southwest China
<p>A high-precise 230Th dated stalagmite from southwestern China was used to reconstruct the changes of ASM and regional hydrological conditions since the last interglacial (3.6–118.1 ka BP) by the coupled δ18O and δ13C. </p>
Stalagmite TS9701 and TS9501 δ18O and δ13C dataset
<p>Here we present results of stable isotope data of two stalagmites (TS9701 and TS9501) from Shihua Cave (latitude 39´47°N, longitude 115´56°E; altitude 251 m a.s.l. at the entrance), northern China, during the past 2000 years. The age model of both stalagmites is based on lamina counting. </p>

Stalagmite
# SHCMS: M.00189 **Stalagmite** Small stalagmite. Unknown origin but thought to have been collected in the late 19th century. Age: recent. Length 18.5cm Width 14.4cm Depth 14.5cm. Imaged using a canon 5DS R and Stackshot 3x with turntable to provide 108 images which were then processed using agisoft photoscan at high levels. If you like this model or any others we produce we'd love to hear from you and how you've used them. Source: Objaverse 1.0 / Sketchfab
